This entry is being used for tracking a regression from 2.6.38. Please don't
close it until the problem is fixed in the mainline.
Still present in -rc5
Still present in -rc6
Still present in -rc7.
Still unresolved and present in 2.6.39.
Still cannot use kernel newer than 2.6.38. That any kernel (intel) developer can say how resolve this? This bug has been over a month, and still has the status of "new".
Your monitor doesn't supply a valid EDID. Attach an Xorg.log+dmesg from a working kernel so that I can see why it might have been judged invalid.
Created attachment 60872 [details]
dmesg from 2.6.38
Created attachment 60882 [details]
Xorg.log from 2.6.38
Result of bisection:

drm/i915: Enable GMBUS for post-gen2 chipsets
With the recent SDVO fix, this is working on all the machines I have to
hand - except for an 845G.
