[OpenAFS-devel] Ubuntu Linux and Open Afs 1.3.71

[Michael McCabe]

I'm trying to get OpenAfs 1.3.71 to runn on Ubuntu Linux (Debian Based 
Distro).   I've succesfully built OpenAfs and loaded the kernel module 
but when I go start the afsd is segfaults and outputs the following 
information to dmesg.  It also appears to be populating the cache.

Thanks for the help

Mike
