GPU Crash Dump

GPU sporadically hangs during normal desktop usage, but recovers and a crash
dump is created (see attached file). I'm using kernel 3.14.0 on Gentoo Linux
with KDE Desktop. In my xorg.conf I have the option 'TearFree' enabled and
disabled any tearing prevention mechanisms in the window manager (KWin).
