           Summary: Watching Sintel in 2K resolution via VAAPI results in
                    GPU Hang and memory allocation issues
           Product: Drivers
           Version: 2.5
    Kernel Version: 2.6.35.4, 2.6.35.7
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - Intel)
        AssignedTo: drivers_video-dri-intel at kernel-bugs.osdl.org
        ReportedBy: jak at jak-linux.org
        Regression: No

I tried watching Sintel in 2K resolution using VAAPI; this caused a GPU hang.
debugging the GPU hang was not possible, as reading i915_error_state failed
with the message that not enough memory could be allocated.

The following dmesg logs show the hang and the trace from running cat on
i915_error_state.

Result from Debian Kernel based on 2.6.35.4
