--- Comment #4 from Jordan Justen <jljusten at gmail.com> ---
Some debug info:

Increasing STATE_SZ from 16k to 32k allows the "-benchmark"
to run for about 30~60s before the GPU hang. At 16k, it hangs
within ~10s.

Increasing STATE_SZ from 16k to 64k allowed it to run for
about 30~60s before hitting an assert:
DirtRally: intel_batchbuffer.c:1063: brw_state_batch: Assertion `offset + size
< batch->state_bo->size' failed.

I also tried increasing BATCH_SZ to 32k, but it did not appear
to make a difference.
