Hello, the following kernel-oops message I've found in my syslogs. As it's a production system, I'd very happy for a feedback/help. If you need further information, please let me know. As I'm not on the list, please cc: me. Christian. ---------------------------------------------------------------------------- Christian Mudra Just remember what your mother always told you: [EMAIL PROTECTED] "When you open windows you let in bugs". ======================= 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.
