--- Comment #5 from Nicolai Hähnle nhaehnle@gmail.com --- 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!

--- Comment #8 from Nicolai Hähnle nhaehnle@gmail.com --- Thanks. Are you sure you ran with GALLIUM_DDEBUG=pipelined? That would make finding the bug much more likely...
