[OpenAFS] afsd, openafs-1.2.0, linux kernel 2.4.9, Pentium problem

[Dr A V Le Blanc]

I last reported this for openafs 1.1.1 on Aug 22, and the suggestion
was that this was caused by incompatible structs which would be fixed
in openafs 1.2.0.  I am now using kernel 2.4.9 with the openafs-client
software in the standard 1.2.0-0.potato1 .deb, and with
openafs-modules-2.4.9 compiled from the openafs-modules-source .deb.
When 2.4.9 boots, everything runs properly until openafs starts.
Here is the dump at the result of running it through ksymoops.
