| |
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 during 1 or 2 days until i have an weird Oops. I have rebooted the machine 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
