this is the command causing the oops:

tar cf - . | gzip -c > backup.tar.gz

the dir in which tar is looking for files is exported via nfs (not knfsd) to
other hosts.

kernel 2.4.[3-8] usually die at this point.no network,no console,caps lock and
scroll lock are blinking
on keyboard...

gcc used to compile kernel:
Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/egcs-2.91.66/specs
gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)

any hints ?
tell me if anyone needs more info..

please cc me if possible,i'm not subscibed to the list.
this mail is going to xfs-mailing list also..

thanks,
gerald weber
