Comment 55 for bug 404064

This error is NOT harmless to me: after resuming from sleep the screen is extremely dark, so dark I first thought it was blank! The funny thing is I cannot even reach such a darkness level in normal conditions.

Disabling KMS with "i915.modeset=0" solves the problem.

Except for the unusable dark screen everything always works fine even after resume: compiz, Ctrl-Alt-FN, etc.

I have this message at boot time AND at resume time, WITHOUT the page table error.
