Hi,
I'm running potato
Linux cerber 2.2.19 #1 Sat Jun 9 13:04:06 EST 2001 i686 unknown
and I'm experiencing multiple very bad crashes. Everything started when
I was uploading a big file on the server from a laptop connect the same
10Meg hub.
The crash looked as follow :

The server was used as a router/firewall connected to a cable modem. The
installation was not very stable and I rebooted a few times over the
last month so
I cannot say for sure that the problem wasn't there before.
Whe nI rebooted it, I got some file system corruption ( I have 7
partitions for <root> /var /usr /tmp /home /opt <swap> ). The problem
couldn't be corrected automatiquely and I went in single mode to run
fsck manually.
This lead to another crash which is perfectly reproducible. I first lost
my /opt partition and after rebooting a few time, the /usr started to
give the same problem. This crash looks as follows :

I can forward all the logs but I've allready tried to send it yesterday (
log.tgz) and it didn't come through. The server no longer
exists, I remove the HD yesterday and put it on another pc and
reinstall. The problem reappeared as soon as I put it back in place.
I suppose this is a H/W problem, do you have any idea on the root cause
of this ?
Thanks in advance for your help,
Vincent Guffens
