          Priority: medium
            Bug ID: 57677
          Assignee: intel-gfx-bugs at lists.freedesktop.org
           Summary: SNB gpu gets stuck at 100% active
        QA Contact: intel-gfx-bugs at lists.freedesktop.org
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: tiagomatos at gmail.com
          Hardware: Other
            Status: NEW
           Version: unspecified
         Component: DRM/Intel
           Product: DRI

Data points:
* Intel(R) Core(TM) i7-2620M CPU @ 2.70GHz
* kernel 3.7.0-0.rc7.git0.1.fc19.x86_64

(I've seen this happen with stable 3.6.x kernels as well)

It seems to happen at random boots, I'd say 1 out of 5 boots. The laptop fan
keeps blowing, the temperature doesn't go under 65C, top says that the cpu is
mostly idle and powertop says gpu is 100% "active" or "powered on".
