Looks like the one I hit recently as well:

http://lists.freebsd.org/pipermail/freebsd-fs/2014-July/019843.html

This lock should probably be excluded from the DEADLKRES.

I have not had time to follow-up on it, but it's a trivial thing to add
it to the list.

The first thing that I'd like to see is (in kgdb):

set $td=(struct thread)0xf8002abeb000
tid $td->td_tid
bt

That will show us the backtrace of the thread that was blocked for so long.

Most useful would be the "show alllocks" from DDB.  Getting the lock
information from kgdb is rather more annoying, though jhb has some gdb

'allchains' command from gdb6 is the one in question, but it's been a
