ReiserFS freeze and corruption

[Ian Zink]

About 15minutes ago now, I was merrily gzipping a 370 meg file. I was
checking the progress doing "du file." At about 260 megs I did a "du
file" and the du failed to respond. I tried to ctrl-c du and then gunzip
to no avail. I tried to open a new console to forcibly kill the process.
It wouldn't open. It seemed anything trying to touch the file system
would fail. I then switched to to the text console tried to login from
there, and it froze. Finally, I sucumbed to the fact my system was in
fact going down. I tried to sync the file system alt-sysrq-s. However, I
did not receive the tale-tell "sync" noise. I tried it again... no go. I
tried to flip back into my X session, where in everything just flat out
froze. Upon rebooting (alt-sysrq-b), I received the message reiserfs was
going to roll back its log:

Replay starting
Replay Failure
03:02 rw-1 want=1075572264 limit=6401902

Reiserfs: run fsck.

I managed to find a CD-rescue disk with reiserfs fsck. Upon running it,
it rolled back the journal ( which apparently the kernel couldn't do)
found errors and told me to rebuild the tree. Because I now fimiliar
with the rebuild tree behavior of fsck(that is, you lose random files),
I decided to not go that route... I ran reiserfsck again with the -x
parameter, and it said no errors found. So some how.. the errors
disappeared. Okay. Now everything _seems_ to be intact. However, as
another person pointed out, aparently with reiserfs when things fail you
can random file cross-tamination when reiserfs replays its logs. 

Now for a few details:
Kernel: 2.4.10
gcc version 2.95.4
IBM Deskstar IBM-DTTA-371440
hdparm -X66 -m16 -u1 -c1 -k1 -d1 /dev/hda
Chipset:  Intel Corporation 82371AB PIIX4 IDE
These messages right before the crash:
