Hi,
This was my first attempt with Linux 2.6, so the userspace environment was still predominantly 2.4 when this happened. The machine is a dual P4 Xeon with 1 GB RAM, ACPI and HT enabled:

And I'm afraid that's all the information that I have, except that I was trying to export an NFS mount from this machine at the time and was failing miserably. (I suspect that this might have been because "ifconfig lo 127.0.0.1" hadn't created an entry in the routing table... if that makes any sense?) The last entries in my log file were:

There doesn't seem to be a ksymoops for 2.6. Is there anything else I need to do to this oops?
Chris
