[Bug 666218] [NEW] kernel oops i915_gem_object_unpin+0xc1/0xd0

[Luka Renko]

Public bug reported:

I get occasional hangs of my X200s laptop - I cannot say what triggers
the bug, but it happens roughly every couple of days, sometimes even
several times per day.

My laptop is constantly docked/undocked and put to sleep (suspend to RAM) and some feeling is that this may increase the probability of hang.
Also, running VirtualBox (with Windows 7 guest) may increase the occurence - but this is just a feeling.
