I need help or suggestions with the following problem. I'm getting desparate!
(Maybe this would better be posted in one of the comp.os.linux newsgroups, but
since I don't understand what's happening, I can't rule out that it's somehow
Debian-specific.)
I have a Linux root partition on my (first) IDE drive; I also have an external
SCSI disk that I use for backup and testing. The SCSI disk has two primary
partitions (sda1 and sda2). Lately when I try to mount the first SCSI
partition (sda1), my machine freezes (requiring a hardware reset), sometimes
after reporting a segmentation fault and a message such as:
Unable to handle kernel paging request at virtual address de2cd460
The second partition on the SCSI disk mounts without problems, and behaves
normally.
I can run fsck on the first partition, and it shows up clean (even with -f).
Moreover, I also have Linux installations on each of the two SCSI partitions,
and I'm able to boot normally from them both, and mount all of my Linux
filesystems, including /dev/sda1, without any trouble.
Can anyone explain what might be causing this behavior, and/or how to fix it?
Failing that, can anyone suggest how to go about diagnosing the problem?
Following are some more details.
SOME HISTORY:
This all began two days ago, when I tried to mount my Jaz disk (/dev/sdb), and
all hell broke loose. I've since decided the Jaz disk must be defective,
since I can't access it from anywhere, including the SCSI adapter's BIOS. But
I don't understand how relates to the problem with /dev/sda1. Until two days
ago, everything had been working fine for months, including the Jaz disk and
the /dev/sda disk.
SYSTEM SPECIFICS:
INTEL Pentium
48 MB RAM
64 MB swap partition
SCSI adapter: Adaptec AHA-2940
External drive is a Quantum LPS340S (from LaCie).
IDE drive has Debian 1.1 with Linux kernel 2.0.20 and also 2.0.0
/dev/sda1 has Debian 1.1 with 2.0.0 kernel
/dev/sda2 has Debian 1.3 with 2.0.29 kernel
All partitions are less than 80% full.
THINGS I'VE TRIED:
I ran fsck and repaired damage to /dev/hda3 (the Linux root partition on the
IDE drive) after each crash.
I tried booting an old 2.0.0 kernel I have on the IDE drive, with the same
results.
I re-installed the 2.0.20 kernel from a Debian package (that I had built
with kpkg last time I compiled the kernel). Nothing changed.
Thanks in advance for any advice!
