--- Comment #1 from Mark Johnston <markj@FreeBSD.org> ---
We're panicking because an idle thread is processing callouts and apparently
taking too long.  Unfortunately I can't see what it was actually doing.  Th=
ere
aren't many users of C_DIRECT_EXEC but it's possible the thread is somehow
stuck in a callout handler.  It's possible that some memory corruption is
causing callout_process() to loop infinitely on a callout list.

I don't think it'll be easy to debug this without a vmcore:
