--- Comment #5 from Alain Perrot alain.perrot@gmail.com 2010-11-21 08:22:49 PST --- With kernel 2.6.37-rc2 and option radeon.no_wb=1, it seems that there is no GPU lockup with the OpenArena benchmark and both the r600g and r600c Mesa drivers.
With the same kernel and without that option, the OpenArena benchmark locks the GPU with the r600g driver (runs fine with r600c).
