[Intel-gfx] Screen not turned on in kernel 2.6.35

[Paul Neumann]

Hi,

when I use kernel 2.6.35 my screen (connected via DVI) is not turned on. Everything else works fine so I can ssh into the machine and safely shut it down. This did not happen with 2.6.34. However I know that the issue is caused by that commit

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=b1083333de5357577c5ec55df6c7efa17bee41c7

If I revert that patch everything works as expected.

My graphics card is

00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03)

The interesting dmesg part is

i915 0000:00:02.0: BAR 6: can't assign [??? 0x00000000 flags 0x0] (bogus alignment)
[drm] failed to find VBIOS tables
[drm] initialized overlay support
No connectors reported connected with modes
[drm] Cannot find any crtc or sizes - going 1024x768
Console: switching to colour frame buffer device 128x48

and xrandr shows

Screen 0: minimum 320 x 200, current 1024 x 768, maximum 4096 x 4096
VGA1 disconnected (normal left inverted right x axis y axis)
DVI1 disconnected (normal left inverted right x axis y axis)
