I just switched to using HDMI with my media center, and its causing a 30+ second delay in the screen turning on, as well as a 7 second delay in the X startup when it tries to fetch the EDID information. Basically I don't get any picture at all once KMS initializes until after X has been up a few seconds.
The odd thing is the monitor seems to think something is going on, since it doesn't go to sleep or display its "No Signal" OSD, but just after X starts up, it pops up the "Input detected/switched" OSD, and the picture appears.
The bios, grub2 (in both text mode and graphics mode), and the initial linux kernel messages all display fine and immediately. Its only once KMS and radeondrmfb initializes that there's a problem (at least till X starts up).
I've just built with a vanila 2.6.38.4 kernel from the stable git repo, and have played with some EDID settings, trying to disable edid where I could thinking thats what caused the problem. That doesn't seem to be the case though. I also tried playing with the video= kernel option, trying to force disable VGA-1, and set a static mode for HDMI-A-1, but if I try, it seems to force disable HDMI-A-1 instead of force the mode.
With a DVI-D cable instead, the problem goes away.
Attached are the dmesg and xorg.log files for the latest boot with HDMI (no video= parameter, and EDID enabled, most settings at defaults).
What exactly would cause this, and is there a way I can fix it?

I've been playing around with it more, and got it to not blank the screen after KMS init, /once/. So far no luck repeating that success.
I've tried late, and early kms init, and currently have the radeon module and firmware compiled into the kernel. Boot times at least are fairly decent, about 8-10s till X starts, but about 25-35s till anything shows up.
Some strangeness, I have the kernel set to force the hdmi output to on, with a very specific mode, that X tends to like, the vga port is forced disabled. X is set to ignore EDID, and also set to that specific mode that it tends to auto set itself. Regardless X still wants to pause for 7s 2-3 times while processing EDID info.
I've attached the new dmesg and xorg logs from the latest attempts.
Note, this only happens with KMS, with HDMI. disabling KMS, or using DVI makes the problem go away. Even grub's own graphical mode works fine, its only once KMS inits that things go bad, and its not till after X is up for a few seconds that something displays on my screen.

Please boot with drm.debug=4 and attach dmesg it should be more verbose. You might also want to try booting with radeon.audio=0
Hi, attached both one with just drm.debug=4, and one with that and radeon.audio=0.
Now, I'm guessing its a bug in my monitor claiming it can do HDMI audio? As setting radeon.audio=0 seems to have fixed the blanking problem. And the dmesg logs seem to claim that radeon thinks it can do HDMI audio.
It also seems to be ignoring the mode I've requested via the video= param. It at least sees that I want it forced enabled, but claims its 0x0? Or at least it seems its picking the preferred mode.
Still have X blocking for up to 14s though.
Theres also a bunch of repeated log messages from drm now, every second about it seems to spam the following lines: (the last one is repeated a bunch of times, with FB:44 or FB:42)

Ok, a bit more news. My monitor does indeed support audio, at least it has volume buttons, so I assume it has speakers, and should support HDMI audio (I have never used it though).

Most likely the driver is sending the wrong packets for hdmi audio. Until that gets fixed up, it's probably best to disable hdmi audio if it's not working for you.

I've been playing around with it more, and got it to not blank the screen after KMS init, /once/. So far no luck repeating that success.
I've tried late, and early kms init, and currently have the radeon module and firmware compiled into the kernel. Boot times at least are fairly decent, about 8-10s till X starts, but about 25-35s till anything shows up.

[ 31.330033] [drm:output_poll_execute], [CONNECTOR:13:VGA-1] status updated from 2 to 2 [ 31.435455] [drm:radeon_atombios_connected_scratch_regs], DFP1 connected [ 31.435463] [drm:output_poll_execute], [CONNECTOR:15:HDMI-A-1] status updated from 1 to 1 [ 31.437391] [drm:drm_mode_addfb], [FB:42]
Cheers, Jerome
Ok, a bit more news. My monitor does indeed support audio, at least it has volume buttons, so I assume it has speakers, and should support HDMI audio (I have never used it though).

Please boot with drm.debug=4 and attach dmesg it should be more verbose. You might also want to try booting with radeon.audio=0
Hi, attached both one with just drm.debug=4, and one with that and radeon.audio=0.
Now, I'm guessing its a bug in my monitor claiming it can do HDMI audio? As setting radeon.audio=0 seems to have fixed the blanking problem. And the dmesg logs seem to claim that radeon thinks it can do HDMI audio.
Most likely the driver is sending the wrong packets for hdmi audio. Until that gets fixed up, it's probably best to disable hdmi audio if it's not working for you.
Ok. I'll do that for now, since I have no need for HDMI audio atm. My receiver is only capable of Dolby Pro Logic input, so eh.
Would be nice to fix the xorg pauses. And whatever is causing the massive amounts of drm log spam (yes, I could disable drm.debug, but that would just hide the issue, as whatever it is, will keep doing whatever it is doing regardless).
Any hints on where to look to fix the stalls when the xorg radeon driver starts up?
Is the Xserver block or is it just that there is no picture ? ie when you see somethings on the screen is it directly the gnome login screen or what ever should come first ? or do you then see gnome loading ?
If it's just black and then you directly got gnome-shell it's likely that your tv doesn't live hdmi mode change and take time before showing the picture.

I can see X start up, the cursor shows up, but it just pauses for a few seconds, then once the wm is up, it pauses for a bit again.
Here's some log info from Xorg that I think might be relevant:
7 second wait: [ 16.161] (II) No input driver/identifier specified (ignoring) [ 23.725] (II) RADEON(0): EDID vendor "BNQ", prod id 30990
1 second: [ 23.726] (II) RADEON(0): Modeline "1920x1080"x0.0 74.25 1920 2558 2602 2750 1080 1084 1089 1125 +hsync +vsync (27.0 kHz) [ 24.620] (II) RADEON(0): EDID vendor "BNQ", prod id 30990
6 seconds: [ 24.631] (II) RADEON(0): Modeline "1920x1080"x0.0 74.25 1920 2558 2602 2750 1080 1084 1089 1125 +hsync +vsync (27.0 kHz) [ 30.206] (II) RADEON(0): EDID vendor "BNQ", prod id 30990
It actually prints out the EDID information 5 times. Once at the beginning, and theres no discernible pause, then later on at the end, it prints out the EDID/DDC information 4 more times, with 3 pauses, once before the second print out, once between the second and third, and once between the fourth and the fifth.
[ 15.849] (II) RADEON(0): EDID for output HDMI-0 [ 15.849] (II) RADEON(0): Manufacturer: BNQ Model: 790e Serial#: 21573 [ 15.849] (II) RADEON(0): Year: 2009 Week: 6 [ 15.849] (II) RADEON(0): EDID Version: 1.3
This is what led me to believe it might be related to EDID. Thought maybe there was some glitch causing kms+xorg to not like my monitor's EDID info, but it seems it likes it just fine, so much it asks for it 4+ times (kms looks, then x prints it out 5 times, possibly actually fetching it 3+ times).
Also, I have it setup to auto boot into KDE without compositing enabled, using startx in an init script. I'm thinking of switching to icewm or something equally light weight, to see if maybe its KDE causing one of the pauses (it didn't used to pause like this, before I updated to 2.6.38).
Last bit of info, my "TV" is actually a 24" 1080p LCD monitor.

Are you sure it's X/ddx and not kde or some desktop daemon loading/polling things? Does it pause the same way if you start plain X with twm or an xterm?

Ok. I'll do that for now, since I have no need for HDMI audio atm. My receiver is only capable of Dolby Pro Logic input, so eh.

Is the Xserver block or is it just that there is no picture ? ie when you see somethings on the screen is it directly the gnome login screen or what ever should come first ? or do you then see gnome loading ?
If it's just black and then you directly got gnome-shell it's likely that your tv doesn't live hdmi mode change and take time before showing the picture.
I can see X start up, the cursor shows up, but it just pauses for a few seconds, then once the wm is up, it pauses for a bit again.
Are you sure it's X/ddx and not kde or some desktop daemon loading/polling things? Does it pause the same way if you start plain X with twm or an xterm?
Ok, it seems its the xrandr fetching. Not 100% sure, but thats the most probable cause. Plain old twm+xtern gives no pause or delay.
Adding anything that uses xrandr will cause a delay, multiple if its done more than once (say from KDE, and XBMC, and whatever else). Except if its the xrandr cli tool, just fetching the info with it doesn't cause a problem. Which is odd, neither XBMC or KDE would actually use it to set the mode, just fetch info.
When I have it set to load twm, and xbmc, I get a delay again, and in xbmc's log, it happens right before the xrandr info is printed out.
Also it seems the page flipping stuff might not be working as it should? XBMC complains it times out waiting for a flip:
WARNING: CRenderManager::FlipPage - timeout waiting for flip to complete
All of this is new as of my upgrade to 2.6.38. If I pause a video it takes a couple seconds for XBMC's little paused graphic to show.

It actually prints out the EDID information 5 times. Once at the beginning, and theres no discernible pause, then later on at the end, it prints out the EDID/DDC information 4 more times, with 3 pauses, once before the second print out, once between the second and third, and once between the fourth and the fifth.

This is what led me to believe it might be related to EDID. Thought maybe there was some glitch causing kms+xorg to not like my monitor's EDID info, but it seems it likes it just fine, so much it asks for it 4+ times (kms looks, then x prints it out 5 times, possibly actually fetching it 3+ times).
Also, I have it setup to auto boot into KDE without compositing enabled, using startx in an init script. I'm thinking of switching to icewm or something equally light weight, to see if maybe its KDE causing one of the pauses (it didn't used to pause like this, before I updated to 2.6.38).
Last bit of info, my "TV" is actually a 24" 1080p LCD monitor.

I just switched to using HDMI with my media center, and its causing a 30+ second delay in the screen turning on, as well as a 7 second delay in the X startup when it tries to fetch the EDID information. Basically I don't get any picture at all once KMS initializes until after X has been up a few seconds.
The odd thing is the monitor seems to think something is going on, since it doesn't go to sleep or display its "No Signal" OSD, but just after X starts up, it pops up the "Input detected/switched" OSD, and the picture appears.
The bios, grub2 (in both text mode and graphics mode), and the initial linux kernel messages all display fine and immediately. Its only once KMS and radeondrmfb initializes that there's a problem (at least till X starts up).
I've just built with a vanila 2.6.38.4 kernel from the stable git repo, and have played with some EDID settings, trying to disable edid where I could thinking thats what caused the problem. That doesn't seem to be the case though. I also tried playing with the video= kernel option, trying to force disable VGA-1, and set a static mode for HDMI-A-1, but if I try, it seems to force disable HDMI-A-1 instead of force the mode.
With a DVI-D cable instead, the problem goes away.
Attached are the dmesg and xorg.log files for the latest boot with HDMI (no video= parameter, and EDID enabled, most settings at defaults).
What exactly would cause this, and is there a way I can fix it?
Most likely, the monitor doesn't like the hdmi packets it's getting from the GPU. If you don't need audio, boot 2.6.38 or newer with radeon.audio=0
