Hi! I'm having a problem with an 8.1-RELEASE #0 amd64 machine.
Three weeks ago, it had a kernel panic, which I was too tired to properly
capture. On reboot, I forgot to run fsck in single user mode; about 12-14 hours
later it crashed complaining that the background file system checks were
inconsistent.
A day later it crashed with a "server double fault"; I was unfortunately on the
way to a meeting, along with all of my technical co-workers, so I wasn't able
to see the screen, and it was being reported by someone who was poorly equipped
to give a good report.
A few days later, it had hung (it didn't respond to input), and I needed to
hard restart.
A few days later, the same thing happened.
Last weekend, on Friday evening it complained about the hard disk controller
disappearing (at least, as far back as I was able to go in the screen buffer).
Saturday night, I finally got a kernel panic that I captured; after this, I
turned on core dumps.
However, last night, it crashed again, and tried to write out a core, but
didn't succeed.
The kernel panic from Saturday night was:
panic: unknown cluster size
cpuid = 0
Uptime: 1h49m37s
Cannot dump. Device not defined or unavailable.
aac0: shutting down controller...
Fatal trap 12: page fault while in kernel mode
cpuid = 9; apic id = 10
fault virtual address = 0x1d
fault code = supervisor write data, page not present
...
current process = 12 (irq256: em0)
trap number = 12
done
Last night's:
Fatal trap 12: page fault while in kernel mode
cpuid = 9; apic id = 11
fault virtual address = 0x8098f90e
fault code = supervisor read data, page not present
...
current process = 97530 (taper)
trap number = 12
panic: page fault
cpuid = 9
Uptime: 3d21h24m57s
Physical memory: 12211MB
Dumping 2942MB:
Note that there was nothing after the "Dumping 2942MB:"; the cursor was sitting
just after the colon. On reboot, it did not find any cores to save to disk (I
did have to boot single user and fsck -y; is it possible that this interfered
with the core dump? if so, how do I fix this?).
I tried, this morning, to run memtest86, however both 3.5 and 3.4 just give
loud annoying beeps, not displaying anything on screen (not even a menu; once I
get past the boot loader from the memtest86 cd, it just starts beeping).
Any suggestions?
Thanks,
Ricky
