The monitor goes blank, and the system becomes totally unresponsive as soon as the radeon module is loaded, if I boot 3.12.4 with radeon.dpm=1 or I boot 3.13-rc5 without radeon.dpm=0.

Did dpm ever work on your board? Just to clarify, does 3.13-rc5 fail to boot even with radeon.dpm=0? Please attach a copy of your dmesg output, Xorg log, and vbios. To get a copy of your vbios: (as root) (use lspci to get the bus id) cd /sys/bus/pci/devices/<pci bus id> echo 1 > rom cat rom > /tmp/vbios.rom echo 0 > rom

Unrelated. That bug is about rv6xx asics. Your chip is a BTC part.

This is the first time I tried dpm, and it didn't work. Without dpm, the card works fine with both kernels.

--- Comment #6 from Juan Orti j.orti.alcaine@gmail.com --- I have the same problem with a Radeon HD6870 and kernel 3.12.6-300.fc20.x86_64 in Fedora.

I cannot boot with radeon.dpm=1. I see the kernel booting but the monitor goes black quickly. Sometimes I see the Xorg loading the wallpaper, but suddenly the image gets corrupted and the monitor goes black.

I have added this patch to the Fedora kernel 3.13.0-0.rc7.git2.1.fc21.x86_64 and the results are the same, sometimes it halts while the kernel is booting, and other times I can even login in KDE, but suddenly the screen is corrupted and goes black.

I attach some logs of when I was able to boot and take them.

Are things any better with my 3.14 branch? http://cgit.freedesktop.org/~agd5f/linux/log/?h=drm-next-3.14

I've been using that branch at commit 0279ed19bd962434d334f5eeb16d14fdd9459a00 and things seems a little better but it keeps crashing with my Radeon HD 6870.

Most of the time, the kernel boots, but sometimes it freezes right at the start. First thing I notice with that kernel it's that I see the Tuxs for a second before Plymouth, maybe it's something related to the initrd, I don't know. I'm able to log in and even sometimes load a 3D game and play, but it always end crashing after a few seconds.

I've trying to do a kdump, but the system is totally unresponsive.

What can I do to help?

I don't know if this helps, but I tried your branch (at 4a8ee429cab), and it fails different. For some reason it calls itself 3.13-rc4+, and it defaults to dpm=0, I hope these are not a problem. When I enable dpm, the screen doesn't turn off when the radeon module is loaded, but as X starts, the screen goes black with 1px blue vertical lines at every 8th pixel. I tried 3 times, the same result.

I don't have glamor now, when I'll have some time I'll try with it.

The same here with a Radeon HD 6870. I can start KDE, but it crashes with vertical white strips over a dark background.

Great! it works very well, I've been using it for an hour, playing 3D games with no stability problems. The temperature also is 10-20 ºC lower than before.

This kernel is your branch drm-next-3.16 at commit 4366f3b5f5a971cf348c298716b2cb29aab6ef4f + patch 102081

I have trying some minutes ago 3.14.12 kernel that have your patches included, I think. But same issue : the system reboots early in the sequence boot.

Or my bug is different or it is the same and your patches does not fix it. Only radeon.dpm=0 on the kernel command line fix it.

You have an APU. This bug is specifically about dpm on BTC discrete GPUs. It sounds like you are seeing bug 72921. Please try the patch on that bug.

You are right and the last patch of bug 72921 fixes my bug issue. Thank you very much.

--- Comment #38 from almos aaalmosss@gmail.com --- Attachment 102081 fixes the "hard lockup with small vertical blue stripes" issue, when applied to 3.15.4, and AFAICS dpm works fine.

The new problem is that I get kernel panic after a few hours if dpm is enabled. With the good old profile method the system is stable.

Attachment 102081 [details] fixes the "hard lockup with small vertical blue stripes" issue, when applied to 3.15.4, and AFAICS dpm works fine.

The new problem is that I get kernel panic after a few hours if dpm is enabled. With the good old profile method the system is stable.

Could you test with latest kernel 3.16 RC (the patch is already included)? I have been running kernel 3.16-RC4 with this patch for Cayman and I don't get any lockups anymore. I've been running my system for a few days (games, movies and so on) without problem.

Can you get a copy of the panic? I think it may be related to the page flipping changes in the last couple kernels. It's not likely dpm would cause a panic.

It seems I spoke too soon. 3.15.4 panics even without dpm.

So it is a different bug from the current one. Alex Deucher may be able to tell you if your screeshot confirms his suspicions. However, if everything still runs fine about dpm with the patch applied, I suggest you close the current bug and, if needed, you open a new one.

I'm not sure this panic has anything to do with the GPU driver.

Me neither, but it makes testing a bit difficult. Not to mention daily work.

Anyway, I'm closing the bug, because the fix for the hang has been found, and it's already landed in most of the stable branches. A big thanks to everyone who contributed.
