        <pre>This sounds a little bit similar to <a class="bz_bug_link 
          bz_status_NEW "
   title="NEW - Reproducible GPU hang on Intel HD5500 — ecode 8:0:0x84df3c1c"
   href="show_bug.cgi?id=92623">bug #92623</a>.  In that bug, Ken was able to
make the hang go away by:

    FWIW, enabling the "Always re-emit all state" block in
    brw_state_upload.c:708 seems to fix this problem.  always_flush_batch=true
    and always_flush_cache=true (way more flushing) have no impact.  This makes
    me suspect missing dirty flags...

Marta: Can you try this to see if it helps?

Ken: Is there any other information that might be helpful?</pre>
