I started a 'make world' today, left for the office.  Checking the
build from work about 4 hours later, I noticed the system had only
been up for 50 minutes.  Apparently this happened during the build
(it's a single user system, so that's all it was doing):

Fatal trap 12: page fault while in kernel mode
fault virtual address   = 0xe8
fault code              = supervisor write, page not present
instruction pointer     = 0x8:0xf0186ffe
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         = Idle
interrupt mask          = net tty bio
panic: page fault

syncing disks... FreeBSD 2.1.0-Development #0: Sun Mar 12 12:56:07 PST 1995
(from 3/10 -current)

Anything else I can do to help assist in debugging this?
