I have Acer 480TG notebook. It have 2 video cards Intel(integrated) and Ati 5470 (discreet).
Problem: linux-2.6.36 - 2.6.38(older version not tested) fails to start X with modeset=1 on both drivers. I see console text(but promt doesn't blank), or black screen.
Tested on: linux-2.6.36-gentoo-r5 linux-2.6.38-rc5 linux-2.6.38-rc6-git4 and 2.6.38-rc3* (Same problem with FedoraTestDay's LiveCD. photo: http://img809.imageshack.us/i/cimg3250j.jpg/ )

--- Comment #7 from Alex Deucher alexdeucher@gmail.com 2011-02-28 19:01:15 --- looks like the vga switcheroo stuff is trying to resume the radeon driver which was never properly loaded in the first place. Dave Airlie might have some idea what's going on.

and I need vgaswitcheroo, because ATI card consume much energy and notebook works 2-2.5 hours (in windows about 6 hours).

--- Comment #9 from Dave Airlie airlied@linux.ie 2011-03-01 07:40:18 --- my first guess is that the ATI card is actually powered off at the start, and we don't try to power on cards to post them.
I need to look at the code to see if I can readback the power state from the hw.

Ok... I bisect kernel. But I am not totally sure in result (because "bad" results does not happens every boot)
Bisect shows that "bad" commit is d3147e86d71e74c93d361988d9441575da71345e but this is trivial patch, so I test commits-neighborhoods and 5222454cf941b09205d502242dd1e44fd62aa551 "bad" too.
PS: after bug happens kernel(?) prints to console something like "__pm_runtime_resume() return 1"
PPS: https://bugs.freedesktop.org/show_bug.cgi?id=36003 looks like this bug

--- Comment #12 from Sebastien Villemot sebastien.villemot@ens.fr 2011-04-11 21:46:12 --- I am affected a quite similar problem.
I have a desktop PC with 2 graphics card: one Intel (bundled within i3 core cpu), and one Radeon.
Using kernel 2.6.38 (Debian version 2.6.38-3), I get:
Apr 11 22:30:50 brouzouf kernel: [ 5.820704] radeon 0000:01:00.0: Invalid ROM contents Apr 11 22:30:50 brouzouf kernel: [ 5.820790] radeon 0000:01:00.0: Invalid ROM contents Apr 11 22:30:50 brouzouf kernel: [ 5.820817] [drm:radeon_get_bios] *ERROR* Unable to locate a BIOS ROM Apr 11 22:30:50 brouzouf kernel: [ 5.820843] radeon 0000:01:00.0: Fatal error during GPU init Apr 11 22:30:50 brouzouf kernel: [ 5.820866] [drm] radeon: finishing device. Apr 11 22:30:50 brouzouf kernel: [ 5.820868] [TTM] Memory type 2 has not been initialized.
My configuration works fine using kernel 2.6.32 (Debian version 2.6.32-31).
I do not use any special boot option (hence I am using KMS, which is activated by default under Debian).
Let me know if I can help in any way to help debugging this, I really need this to work.
Thanks

--- Comment #13 from Sebastien Villemot sebastien.villemot@ens.fr 2011-04-12 20:53:48 --- Actually I resolved my problem by forcing the loading of the "radeon" module in initramfs, so that the Radeon card is initialized before the Intel card.
Note that I also have to take care of starting the X server for the radeon card before starting the X server for the intel one.

with "ON" - X restarts successfully.
backtraces are very similar... so, I think it is one bug.

--- Comment #16 from Seth Forshee seth.forshee@canonical.com 2011-06-03 13:53:31 --- Adding here some of the information that I added to the freedesktop.org bugzilla here:
https://bugs.freedesktop.org/show_bug.cgi?id=36003
It seems to me that nothing being done currently in the radeon and switcheroo code guarantees that the ATI card is powered on before probing the hardware. I tried adding a call to the ATPX method to turn on power from radeon_register_atpx_handler(), but this doesn't seem to be helping. Can anyone comment on what steps need to be taken to ensure that the card is powered on before proceeding with hardware initialization?

--- Comment #17 from Antonov Nikolay ostinru@gmail.com 2011-06-18 19:11:13 --- I can't reproduce this bug on 2.6.39-git19 and 3.0-rc3. Seems bug fixed. Thanks!
https://bugzilla.kernel.org/show_bug.cgi?id=30052
--- Comment #18 from Seth Forshee seth.forshee@canonical.com 2011-08-31 14:16:18 --- I just completed a bisection with some of the reporters to identify what fixed this, and it came down to this commit:
commit 3448a19da479b6bd1e28e2a2be9fa16c6a6feb39 Author: Dave Airlie airlied@redhat.com Date: Tue Jun 1 15:32:24 2010 +1000
vgaarb: use bridges to control VGA routing where possible.
I can't see why this would have any impact on whether or not the GPU is powered on when nouveau probes it. Is there any explanation for why this appears to fix the issue, or is it likely that it's just changing the timing enough to somehow mask it?
