Description

Hi,

Details:
P4 1.5GB
2.3.2 (28 July)
HAMMER root (/)

----
While doing a 'make reinstall32' in test/vkernel, I got a panic.
Currently I'm trying to reproduce it.
The memfile is 1.5GB so I doubt I could be able to upload it.

Unread portion of the kernel message buffer:

It's possible you tried to do something while a vkernel was still
    running on the disk image, and the UFS image got mangled.  That is
    about the only thing that could cause that sort of corruption.
The vkernel Makefile does issue a fsck when it mounts the vn to try
    to clean up the filesystem (since often people just kill -9 the vkernel
    instead of shutdown/halting it normally).  'make mount' does the fsck
    and mounts the vn and 'make umount' will unmount it.
