closedA new panic on HEAD

Description
Hey everyone,
I accidentally tried to mount a fat32 partition over a directory where
ntfs was mounted, and Ive got a panic. I tried making a core dump but
/var/crash is empty. Ive set dumpon /dev/ad4s1b (swap) and change the
sysctl and it said it was dumping but as I said /var/crash is empty.
Could you try to reproduce it on your box? What am i doing wrong the dumps?
Thank you,
Petr

i guess this is related to <http://bugs.dragonflybsd.org/issue512>. possibly all mounts over a mountpoint panic the box.

Indeed it is probably the same (i remember lockmgr in the trace and
couple of other points)
Thanks,

I'll try to track this down after I get back this afternoon, before
I branch the tree. But if someone else tracks it down first, please
commit!

Try it with rev 1.112 of kern/vfs_syscalls.c, just now committed, and
tell us if that fixed it.
