Here I am again! NFSD died at 11h23, ~12 hours after the last reboot, a
record :-)
I'll try to best answer your questions.

It's in the attached file.
In fact, the Oops was with a new compiled kernel with NFSD in modules... So
the GDB stuff would not work...
So attached is the output of GDB recompiled with NFSD in the kernel. Is it
sufficient for you? It's not the one that was running but just recompiled.
If not, I'll send you a new Oops + GDB output of a RUNNING kernel with NFSD
in the kernel.

I have only ACL patched. You can find them at acl.bestbits.at.
I have tried without them, with exactly the same behaviour.
Thanks
