Hi. My box just crashed with

panic: mtx_lock() of destroyed mutex @ /usr/src/sys/kern/kern_mutex.c:151

This is a ~7 days old -CURRENT with INVARIANTS and i915drm.
Is there any point investigating this? Or should I just csup and hope 
that that will fix it? :)

(I still have a debug kernel and core file if anyone is interested.)

Cheers
Michiel
