As it's a production system, I'd very happy for a feedback/help. If you need
further information, please let me know.

======================= snip here ===========================
[1.] 2.4.5 kernel oops in inode.c:486
[2.] The bug itself happened on a NFS-client, running 2.4.5 while doing
some file access (copy, move).
The corresponding NFS-server is also running kernel 2.4.5, both machines
are using knfsd with NFS v3, and the nfs-volume is mounted static,
no automount. The filesystem on the server is ext2fs.
[3.] knfsd, ext2, 2.4.5
[4.] Linux version 2.4.5 (root@thot) (gcc version 2.95.2 19991024 (release))
