Matt, any ideas offhand?
Arek, can you attach the stderr output from running the game with the environment variable
R600_DEBUG=fs,vs,gs,ps,cs,tcs,tes
with and without the commit in question?
For obtaining the hanging shader, setting GALLIUM_DDEBUG=800 and attaching the created log file is better. The issue would have been pretty obvious from that.
