2.4.4 Kernel Oops and ls+rm segfaults

Hi!

Can anyone tell me, where this oops came from?
The machine is a HP NetServer II lc (EISA+PCI architecture). The distribution is a slackware 7.0 with parts of 7.1 and current.
gcc: 2.95.4 20010319 (Debian prerelease)

I hope you can help me.

Regards,

-Gregor

Pagecache corruption somewhere.
a) what filesystems do you have?
b) is the thing reproducable?

a) pure ext2-fs (sometimes a mounted nfs)
b) Not really. It happend with earlier kernel revisions, too.

I alredy replaced the fs-utils and compiled the kernel at my workstation (with gcc-2.95.3)

If it matters: we have the Compushack FDDI driver installed. It can be found
