--- Comment #1 from Eygene Ryabinkin <rea@FreeBSD.org> ---
Mikhail, good day.

I had just patched DRM w.r.t. off-by-one access that will be provoked by the
userland that is KMS-enabled on the kernel that doesn't support KMS.

The patch is now only in -CURRENT, but you can try to apply
  http://codelabs.ru/fbsd/patches/drm2/fix-drm_drv-off-by-one.diff
to your 10.x sources and rebuild kernel: it may eliminate the panic.

Could you, please, test?
