This should be fixed by revision 1.198 of vfs_syscalls.c. It could
only occur during unmount(), which is why it didn't show up more
often:

Modified files:
sys/kern vfs_syscalls.c
Log:
Avoid sleeping while holding a mutex in dounmount(). This problem
has existed for a long time, but I made it worse a few months ago
by by adding calls to VFS_ROOT() and checkdirs() in revision 1.179.
Also, remove the LK_REENABLE flag in the lockmgr() call; this flag
has been ignored by the lockmgr code for 4 years. This was the only
remaining mention of it apart from its definition.
