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.
