           Summary: [BDW] oops in intel_unpin_fb_obj

           Version: DRI git
          Hardware: x86-64 (AMD64)

            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Intel

netconsole-dump

On the latest -nightly when running the following, a hard hang will sometimes
present itself:

./nexuiz-linux-x86_64-glx -benchmark demos/demo1 -nosound 2>&1 | egrep -e
'[0-9]+ frames'

This has so far been hard to reproduce, so bisection has proved to be futile,
but did finally get it to happen whilst netconsole was running. Please see
attached.
