kmsg: gsraytrace lockup on HD6850
Just noticed the problem today on my HD6850. Unfortunately, it doesn't come
back to life all the time. That is either complete lockup (and reboot) or at
least Xorg being hung in process state D and gsraytrace in state Z. Attached
log produced, when hitting the latter one (though sysrq still worked and
terminal after sysrq-r worked well). The lock contains some of the
sysrq-show-xyz triggers, which are of help maybe (the blocked cat is from
catting one of the radeon sysfs entries). Xorg log only shows event overflows.
GPU hang seems to be 100% reproducable with gsraytrace for me.
Software components being:
media-libs/mesa-9999 (git-4de86e1)
sys-devel/llvm-3.6.2
sys-kernel/vanilla-sources-4.2.0
x11-libs/libdrm-2.4.64
options radeon audio=1 tv=0 dpm=1</pre>
