NetBSD 7.0_BETA (DRMKMS) #0: Mon Oct  6 21:02:13 BST 2014 (slightly older, but same issue). amd64, 8GB RAM.

>Description:
startx works fine and brings up correct resolution, but after running X for a while, the kernel panics. It seems to be random when it happens, but it is reproducible. Same error with up to date -current too.

System panicked: kernel diagnostic assertion "!(obj->base.write_domain & ~(0x000
00002 | 0x00000004 | 0x00000008 | 0x00000010 | 0x00000020))" failed: file "/home
/sborrill/src/sys/external/bsd/drm2/dist/drm/i915/i915_gem.c", line 2833
Backtrace from time of crash is available.
