--- Comment #25 from Maarten Lankhorst <bugs at mblankhorst.nl> ---
The trace checked out, did some annotations on the timings to be sure..

As a hunch I tried to see if the vblank timings were sane, it seems
kms_setmode.basic (vblank timings) is not part of fast feedback.

Farm3-snb with fake monitor (difference is always the same):
(kms_setmode:4749) CRITICAL: vblank interval differs from modeline! expected
16666,7us, measured 16633us +- 3,436us, difference 33,7us (9,8 sigma)

Farm3-snb with real monitor (difference value differs from above, but still
always the same):
(kms_setmode:4826) CRITICAL: vblank interval differs from modeline! expected
16672,7us, measured 16630us +- 1,843us, difference 42,7us (23,1 sigma)
