I get a thoroughtly reproducible (in fact, utterly non-un-reproducible)
panic on boot of recent -CURRENTs. It did this on a cvsup from maybe 2,
3 days ago, and again with one done ~4pm CDT today.
Note: all these messages are hand-copied, this machine isn't in a
situation where it's easy to put a serial console on it :(
Bootup gets as far as:
isab0: <PCI to ISA bridge (vendor:0e11 device:0002)> at device 15.0 on pci0
which immediately suceeds probing xl0. -v doesn't show anything more
revealing. Panic reads as:
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x24000208
fault code = supervisor read, page not present
instruction pointer = 0x8:0xc01456f5
stack pointer = 0x10:0xc02d5ef8
frame pointer = 0x10:0xc02d5f04
code segment = base 0x0, limit 0xfffff, type 0x1b
= DRL 0, pres 1, def32 1, gran 1
processor eflags = interrupts enabled, resume, IOPL=0
current process = 0 ( )
interrupt mask = net tty bio cam
kernel: type 12 trap, code:0
DDB reveals
Stopped at device_probe_and_attach+0x9 movl 0x8(%ebx),%edi
The first few nuggets of creamy goodness 'trace' reveals are:
device_probe_and_attach(24000200) at device_probe_and_attach+0x9
bus_generic_attach(c09e1880, c02d5f38, c0145737, c09e1880, c09e1880)
at bus_generic_attach+0x16
DEVICE_ATTACH(c09e1880, c09e1880, 0, c061cb40, c02d5f48)
at DEVICE_ATTACH+0x25
If previous items in the trace (I think there were around 6 of them)
would be helpful, I can grab them; it's just a pain copying the !&$
things down ;)
Ideas? Trashing it isn't really an option, I use it too much. It's not
a critical server, so I can experiment with patches/etc on it, but it's
my main workstation here, so I'd rather not trash it utterly in the
process.
It's presently up running this 3-day old -CURRENT world and a kernel
from... early March, I think, working fine.
System is a Compaq Deskpro 575, P120 processor, 80 megs RAM, 1 floppy, 1
IDE drive, built-in lnc1 (which doesn't get along with the lnc driver),
xl0 used as net card, parallel port ZIP drive. Kernel config follows:
#
# GENERIC -- Generic machine with WD/AHx/NCR/BTx family disks
#
# For more information read the handbook part System Administration ->
# Configuring the FreeBSD Kernel -> The Configuration File.
# The handbook is available in /usr/share/doc/handbook or online as
# latest version from the FreeBSD World Wide Web server
# <URL:http://www.FreeBSD.ORG/>
#
# An exhaustive list of options and more detailed explanations of the
# device lines is present in the ./LINT configuration file. If you are
# in doubt as to the purpose or necessity of a line, check first in LINT.
