I've been able to get lucky and not get a hard lock most of the time. You HAVE to wait 10 seconds for the drm to reset the GPU. The patch didn't improve or change anything, I've seen those results for a while.
any special commands you append to the radeon driver ? defaults (no special settings) ?
is it compiled into the kernel ? initramfs ?
thanks, will wait next time for 10+ seconds and crossing fingers
