I'm getting a kernel panic on one of my machines. It's reproducable,
occurs on every shutdown. I've swapped out hardware, but the problem
doesn't go away.
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x1c
fault code = supervisor write, page not present
instruction pointer = 0x8:0xc04b51e3
stack pointer = 0x10:0xd52fa780
frame pointer = 0x10:0xd52fa78c
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 297 (syslogd)
trap number = 12
panic: page fault
Uptime: 3m43s
Dumping 512 MB
Note sure if it's relevant, but the user space process in qustion is
always syslogd.
One interesting note, if I try to shutdown during the background
fsck_ufs, no panic occurs but 'Syncing disks' never completes (just
keeps writing numbers).
Below is a backtrace. And in case it's needed my kernel config is attached.
For what it's worth this looks similar to this panic:

Thanks in advance for any ideas...
Cheers,
Nate Nielsen
