panic backtrace

[Colin Percival]

Panic while booting the latest git code: http://imgur.com/fWdooqS

For the benefit of google and other robots which don't index photos:

> panic: Lock drmslk not exclusively locked @ ... i915_gem.c:1029
> 
> ...
> _sx_assert()
> __wait_seqno()
> i915_gem_set_domain_ioctl()
> drm_ioctl()
> devfs_ioctl_f()
> kern_ioctl()
> sys_ioctl()
> amd64_syscall()
> Xfast_syscall()
> --- syscall (54, FreeBSD ELF64, sys_ioctl)

Possibly related: Setting drm.debug=3 seems to make the panic not happen.
