/var/log/messages |grep kernel

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:

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.

kernel boots well without vgaswitcheroo, but radeon doesn't probe due to #15181

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

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.

kernel bisect

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

sorry for my English

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

Apr 11 22:30:50 brouzouf kernel: [    5.820817] [drm:radeon_get_bios] *ERROR*

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

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.

Yes, I can reproduce #15851:
steps:
Crtl+Alt+F1, "OFF" - everything is OK
Stop gdm daemon - OK
Start gdm or X - Freez.

with "ON" - X restarts successfully.

backtraces are very similar... so, I think it is one bug.

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?

I can't reproduce this bug on 2.6.39-git19 and 3.0-rc3.
Seems bug fixed.
Thanks!

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?
