Can you provide an apitrace that reproduces the hang?

That's odd. As an alternative, could you please provide a log with
R600_DEBUG=vs,tcs,tes,gs,ps,cs both before (without hang) and after (with hang)
the problematic commit. Also run with GALLIUM_DDEBUG=pipelined; after the hang,
you should get a message about the hang being detected as well as a file in
~/ddebug_dumps/ that ought to be useful. Thanks!

Thanks. Are you sure you ran with GALLIUM_DDEBUG=pipelined? That would make
finding the bug much more likely...
