>Description:
Whenever I use the shutdown command, I get a fatal trap 12 in
kldunload(). This happens every time, unless I first do a
umount -f /usr, in which case the trap does not occur.
This started happening as soon as I upgraded the machine from a PII-350
on an Abit BX-6 motherboard to an Athlon Thunderbird on a Gigabyte GA-7DX
motherboard. I am using Crucial PC2100 SDRAM on the board.
Here is the traceback from gdb -k /var/crash/kernel.7 /var/crash/vmcore.7:

>How-To-Repeat:
I'm not sure that the problem is repeatable except on an identical
configuration. I can give an account to a kernel developer who wishes
to examine things, but I can't let him/her do live experiments on the
system (it is my firewall and router). I will try patches and report
on their effect.
