--- Comment #2 from Stefan Rink <stefanrink at yahoo.com> ---
I hit this bug on a bhyve with UFS filesystem on 13-current!

 thread 100377 (pid 36752, sh) blocked on lockmgr ufsEXCL
 thread 100078 (pid 22, syncer) blocked on lockmgr bufwaitEXCL

It's still in KDB but I can only access the console via VNC so can't copy/paste
text, dump it or make screenshots.

Trace of the sh process that started this;
sched_switch()
mi_switch()
sleepq_switch()
sleepq_wait()
sleeplk()
lockmgr_slock_hard()
__lockmgr_args()
ffs_lock()
VOP_LOCK1_APV()
_vn_lock()
vget()
cache_lookup()
vfs_cache_lookup()
VOP_LOOKUP_APV()
lookup()
namei()
vn_open_cred()
kern_openat()
amd64_syscall() -
