            Bug ID: 73406
          Assignee: chris at chris-wilson.co.uk
           Summary: [SNA G33/31] xorg/ddx hits assertion `bo->refcnt'
                    failed maybe once per day
        QA Contact: intel-gfx-bugs at lists.freedesktop.org
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: ccr at tnsp.org
          Hardware: x86 (IA32)
            Status: NEW
           Version: unspecified
         Component: Driver/intel
           Product: xorg

Lately my X setup has started hitting kgem.h:341: kgem_bo_submit: Assertion
`bo->refcnt' failed. (also similar asserts of bo->refcnt in other locations of
intel ddx), this happens quite often .. maybe once a day, sometimes even more.
I am not sure what the causality here is, though.

Please instruct in how to help debug this issue.

In re: previous IRC discussions, the badalloc issue still lingers, but this
assert issue is hitting me rather badly.
