Here's an interesting one.  I've been following the 3.0 current tree for
a bit and now, when I go to reboot my machine using shutdown, reboot,
or halt, it starts the shutdown process, kills most of my programs (maybe
all, kinda hard to tell), and panics at the end.  The panics have been:

panic lockmgr: pid 263 not exclusive lock holder 1 unlocking
(pid differs depending on how long it's been running)
and:

panic: unmount: dangling vnode

This has caused me some anxiety, as it doesn't cleanly shut down the
file systems when this happens.  The panics occur every time I go to
reboot.  The wierd thing is that if I reboot via ctrl-alt-del, it
doesn't panic.  I've talked to others running the same level of 3.0
code that I'm running, on similar hardware, and they've not experienced
this.

My hardware:
DFI G586IPC system board
intel triton iii chipset
cyrix 6x86 p166+ cpu
512kb L2 cache
64mb non-parity 60ns ram
adaptec aha2940W pci scsi controller
3com 3c595 pci 10/100 ethernet card
genoa phantom 64v-2001 s3 trio64+ pci video card w/2mb vram
sb16 value edition (not pnp)

Any insight on this would be greatly appreciated.
