Crash (locking against myself) during ntfs mount

Since I updated my kernel on 9/3, I panic when I try to mount an NTFS
volume. The error is "panic: lockmgr: locking against myself". My kernel
lacks WITNESS, although I could build a new one with it if needed. My
previous kernel was built on Aug. 27, so the breakage was during this 7
day period.

I have the full core dump and can get added information. The panic is
quite reliable. All I have to do is issue the "mount -t ntfs /dev/ad0s1
/mnt" command.

I am attaching the kgdb back trace. Hopefully the mailer won't strip it off.
