Hi everyone,
tonight when I started my laptop, i was welcomed with a very nice panic, which
was happening JUST when mounting the filesystems.
Some info:
Fault code : supervisor read, page not present.
current process : 112 (mount)
trap 12
panic :page fault
with nm -m I saw that the following procs where candidates ...
ufsdirhash_build
ufsdirhas_free
ufsdirhash_lookup
Booting with 6.1 Release CD and mounting showed no obvious problems at all, but
the panic could be reproduced every time with this particular kernel (6 days
old). Commenting out /tmp in fstab worked around the problem.
recreating the filesystem in /dev/ad0s1e (my /tmp) solved the problem and now
everything is back to normal. The computer works great as usual.
$ uname -a
FreeBSD ayiin.xxx 6.2-PRERELEASE FreeBSD 6.2-PRERELEASE #14:
Wed Oct 11 14:13:49 EST 2006
root@ayiin.xxx:/usr/obj/usr/src/sys/AYIIN i386
I have a good kernel dump , a copy of /boot/kernel that was being used, and a
dump (dump -0 -a -f usr/ad0s1e.dump /dev/ad0s1e ) of the /tmp partition at the
time (before the newfs, of course). Available for anyone interested.
Is there a bigger issue here? anything I can do to help diagnose / debug this?
TIA!
B
