before login.

works just fine.
if the kernel did not crash, GPU hang will be detected. they might be
related.

[drm:gen6_sanitize_pm] *ERROR* Power management discrepancy:
GEN6_RP_INTERRUPT_LIMITS expected 16110000, was 16000000
[drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
[drm:i915_wait_request] *ERROR* i915_wait_request returns -11 (awaiting 3335 at
3303, next 3336)
