Hello,

I am using 2.4.23 kernel with no patchset. It was the first time i
install a linux distribution on this PC, so i can't tell you if it have
this Oops with an another version of the kernel. It looks to work fine=20
during 1 or 2 days until i have an weird Oops. I have rebooted the machine=
=20
after this but it appears again few days later and despite some reboot.

I haven't include the support for module loadable. I am using Debian
GNU/Linux Woody up to date.

Thanks for you help.
Arnaud Fontaine
