The BUG you were hitting before is on the error collection path which
presumably is still being triggered during boot by a GPU error.
Can you check to see if /sys/kernel/debug/dri/0/i915_error_state has
recorded anything? And if not, wait until it freezes and then please file
a bug report at bugs.freedesktop.org with the i915_error_state, Xorg.0.log
and dmesg.
