[Bug 89246] Flickering and corruption under certain conditions

--- Comment #1 from Chris Wilson <chris at chris-wilson.co.uk> ---
A couple of suspicions here. If the Windows driver is also affected, it may be
bad hardware. (Or just close to the edge of specification!) The flicker itself
may be underruns. If you can grab a video, that would help immensely. If it is
an underrun, they should also be reported into a drm.debug=6 dmesg.

If you disable i915.ko entirely and the problem still persists, then we can say
definitely the hardware is very suspect - but we may be able to workaround the
problem...
