            Bug ID: 91062
           Summary: [SKL] fbo-depth-array causes GPU hangs
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/i965
          Assignee: ben at bwidawsk.net

This bug is the mesa component of
https://bugs.freedesktop.org/show_bug.cgi?id=90854.

We're getting hangs, which the kernel fails to recover from. The hangs only
occur on more recent SKL steppings. The older steppings don't seem to have an
issue.

With all the latest hang fixes for mesa, sometimes the test does complete for
me, but if I run it in a loop, it will hang eventually.

Here is an example of a command which will hang:
bin/fbo-depth-array depth-clear -auto -fbo
