Kernel Panic during 'shutdown -r' on 5.4-p2

From: Nate Nielsen <nielsen_at_memberwebs.com>

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
