--- Comment #37 from David Kellum <dek94 at gravitext.com>  2013-06-19 16:22:01 ---
Confirmed and reproduced with various 3.6+ kernels on Thinkpad T520, i7-2640M,
i915 only, on Fedora. I've stayed on Fedora 17 and started building my own late
series 3.4.x kernels to avoid this. Currently no issue on the following.
Thankfully the issue has not been back-ported to 3.4:

Linux retro 3.4.48-1.dek.fc17.x86_64 #1 SMP Mon Jun 10 18:34:02 PDT 2013 x86_64
x86_64 x86_64 GNU/Linux
