dmesg output showing GPU lockup

Just tried to play WoW against Mesa git, having already set R600_HYPERZ=0 to work around bug #61747. This resulted in a GPU lockup after a few minutes.

git HEAD is:

commit d24819dce8cf6dac23f27df46fabbf756a732229

    i965/vs: Add IR dumping for immediates.
    
    This makes dump_instructions more useful.

Is this a regression?  if so can you bisect?
Comment 2 Marek Olšák 2013-03-21 13:39:00 UTC 
The correct way to disable HyperZ with Mesa master is now R600_DEBUG=nohyperz
Comment 3 Chris Rankin 2013-03-23 17:19:08 UTC 
The same Mesa build plays WoW OK with R600_DEBUG=nohyperz instead.
