Hello!
I've been having a heck of a time getting an ASUS P/I P55T2P4 motherboard
working with my custom 2.2 kernels. I think it's related to the serial
hardware somehow, but I need someone to decode this panic and confirm.
I've included the boot info to help locate where it is. This is captured
from a serial console (-h) output. The message appears just as the system
would pop up the gettys:
configuring syscons: keyrate.
.
Local package startup: Modula-3 sshd.
starting local daemons:xdm pcnfsd msqld bb.

Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x0
fault code = supervisor read, page not present
instruction pointer = 0x8:0x0
stack pointer = 0x10:0xefbffe2c
frame pointer = 0x10:0xefbffe84
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 = 5 (sh)
interrupt mask = net tty
panic: page fault
syncing disks... 22 21 19 10 6 done
I can also get this panic (with the _same_ detail) if I exit X (I have a
serial mouse) or when Kermit quits. I think it's having trouble closing
the serial port.
Disabling either port doesn't help. I can't try disabling both, then I
can't run the apps that force the panic.
Specs on this machine:
ASUS P/I-P55T2P4 motherboard w/ P133 CPU, 32mb RAM
FreeBSD: 2.2-anything
Video: ATI Mach64 GX
SCSI: NCR 53c815
Network: 3com 3c900
Audio: GUS PnP
IDE/Serial/Parallel port board (parallel enabled only)
The machine is otherwise perfectly stable.
One odd note: If I run the 2.2-970206-GENERIC kernel, it works fine. X
complains there's no shared memory or MIT-SHM extensions, but it works.
