The gpu refuses to clear the write fifo. Which means it pretty much
disappeared into nirvana. The kernel _should_ detect this condition and
try to reset the gpu. Furthermore it should dump a useful information into
i915_error_state in debugfs. Can you please attach that (rebooting
obviously destroy the contents of that file)?
Also, your version of your kernel, xf86-video-intel, mesa and libdrm are
relevant.
Yours, Daniel
