--- Comment #2 from Konstantin Belousov <kib at FreeBSD.org> ---
(In reply to daniel from comment #1)
Recompile the kernel with INVARIANTS etc, see the guide at
https://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kerneldebug-deadlocks.html

When the situation occurs, execute 'kgdb <path>/kernel.debug /dev/mem'.  After
that, switch to the thread which hung, with the kgdb command 'thread <id>'. 
Backtrace 'bt' would should you the arguments, find the vnode address which
caused the hang (most likely it is shown as vp), and do 'p *vp', 'p
*(vp->v_bufobj.bo_object)'.
