--- Comment #5 from Kenneth Graunke <kenneth at whitecape.org> ---
Hmm...the Car Chase hangs look like some kind of memory corruption.  I'm seeing
batchbuffers with compute commands where the first part of the batchbuffer is
full of garbage.  The upload BO appears to be directly before it in the address
space, and altering the size of that helps with the GPU hangs (but it may just
be moving the buffers around).  I see corruption in the images when it doesn't
hang, so maybe it's overwriting the image with garbage instead.
