Hi

Last known good: 2.6.38
Failing kernel: 2.6.39-rc3
Subsystem: Intel graphics driver.

Description:
PC should work with 1440x900 resolution. But console (and after) X Window 
start work with 1024x768. 

I attach dmesg and Xorg.0.log with drm.debug=14 log_buf_len=16M options:
http://unixy.pl/maciek/download/kernel/2.6.39-rc1/zlom/kms/

seems that driver cannot detect resolution higher than 1024x768.

Also I boot kernel replace "i915.modeset=1" with "nomodeset" option:
http://unixy.pl/maciek/download/kernel/2.6.39-rc1/zlom/nomodeset/

But then X Window fails to start and got message: "(EE) No devices detected."

Config for 2.6.39-rc3:

Best regards
