[nas-2000] Kernel oopses...

Hello everybody,
I have some problems with my nas as it freezes at unpredictable points.
Has anybody experienced such a problem?
The kernel has the following version: Linux nas-2
2.6.10_dev-versatile926ejs #1 Wed Jan 17 12:02:15 CST 2007
Down below a excerpt from the dmesg-log. In that example, nfsd got some
problems, but I experienced also a crash during smb file access - so it
seems not to be limited to nfs only.
Thanks and a nice weekend,
Oliver
