[Bug 742194] Re: GPU lockup

 

[   12.649270] i915 0000:00:02.0: BAR 6: can't assign [??? 0x00000000 flags 0x0] (bogus alignment)

That's a second problem... this is the gpu lockup that triggered this
bug report.  Unfortunately due to the previous error it failed to
collect actionable data in this case.

[   12.709414] No connectors reported connected with modes
[   12.709422] [drm] Cannot find any crtc or sizes - going 1024x768

...and that's a third problem.  But wtf, haven't seen an error of this
style before.  Can't find crtcs?
