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
Mar 23 11:35:09 m18 kernel: error: [drm:pid968:i915_write32] *ERROR* Unknown unclaimed register before writing to 20a8

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.
