--- Comment #1 from Andriy Gapon <avg at FreeBSD.org> ---
kdb_trap context places certain requirements on code that can be executed.
Apparently drm code (used via vt) is not aware of those requirements.
The easiest solution is probably to amend pause_sbt() to take the 'cold' code
path for kdb_active case as well.
