--- Comment #1 from Ian Romanick <idr at freedesktop.org> ---
This sounds a little bit similar to bug #92623.  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?
