sysctl hw.dri.0.info.i915_error_state

During boot process screen freezes on some time, and I see these lines in dmesg:

Mar 23 11:35:09 m18 kernel: error: [drm:pid12:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU hung
Mar 23 11:35:09 m18 kernel: info: [drm] capturing error event; look for more information in sysctl hw.dri.0.info.i915_error_state

Exactly which Intel GPU model this is about?  Do you still experience the problem with recent FreeBSD versions?  Note that DRM support had moved out of the base system/kernel to the `graphics/drm-*-kmod' and `graphics/gpu-firmware-kmod' ports.

Your report was against 11.0-STABLE which is no longer supported.  Please update to contemporary, supported FreeBSD version and reconduct your tests.

Adding x11@ to CC list so it can be tracked while originally filed under base system/kern.
