While shutting down my FreeBSD laptop, I got this panic:

panic: vinvalbuf: dirty bufs  
at line 921 in file /usr/src/sys/kern/vfs_subr.c

I had just detached a USB mass storage device (umass) and then given the
command "halt", when the panic happened. I may have forgotten to do
umount /mnt, which may have caused the panic ? FreeBSD CURRENT has
worked fine beside this first panic.

			Kind regards,
