kinda long... sorry
I was coping an ISO image via NFS to a directory on an ext3 partition
(dev/hdc2) and the computer locked up as soon as I hit the enter key. I've
had problems before with ext3 and nfs (see FYI below), but this time it was
on a different hard drive (first time was /dev/hda) and this time I got an
oops along with a machine lockup. After hitting the reset button (machine was
dead) I ended up having to delete a mysql index file because fsck couldn't
repair it.
>From fstab -
LABEL=/storage /opt ext3 defaults 1 2
FYI - I ran into some reproducible problems before with ext3 and possibly
NFS. I had a 1365344k oracle database export gzipped down to 263688k and then
made into an ISO image. I'd copy the file from the file server
(2.4.3-SGI_XFS_1.0.1) via NFS , mount the ISO image, and burn it to CD
without any errors being reported. When I'd try gunzip the file from CD, I'd
get CRC errors. I then tried mounting the ISO image and running gunzip and
I'd get the same CRC errors.
I went back to the file server, mounted the ISO image, and had no problem
gunzipping it. I then tried coping the same file again via NFS but gave it a
different name to copy to. Running both diff and cmp told me the files were
different and both couldn't be gunzipped from mounted ISO images.
I could also copy this file to a new file name in the same directory (cp
db.iso timma.iso) and when I ran both diff and cmp, they reported differences
between the two files. I then tried using SCP to copy the file over and I had
no problems. All this was repeatable. I upgraded kernels from RedHat 7.3
stock 2.4.18-3 to vanilla 2.4.19 and problem seemed to go away.
I'd be happy to provide anymore information!

Hmm, that is strange, since unless the index file was just being created
the file metadata (as opposed to the data) probably doesn't change much.
What was the error there?

Have you tried disabling IDE DMA on this system?

You need to run this through ksymoops, otherwise it is just a bunch of
random numbers.

That's usually a hardware or driver, not filesystem, problem. I've
had a couple of environments which have given data corruptions like
that on IDE drivers in UDMA mode but which were fine in MDMA or PIO
mode.

That can be just a matter of the config options used masking a driver
problem. Can you still reproduce with "ide=nodma"? That would
certainly point towards a driver or hardware fault.
