Using debian testing (lenny) and self-compiled 2.6.25 or 2.6.26 kernels, I get the following GPF:

This does *not* happen using 2.6.24 compiled with essentially the same .config file. Using the latest openafs-modules-source: 1.4.7.dfsg1-5.

Odd... I'm on Sid, openafs 1.4.7-dfsg1-5 and 2.6.26.5 without issues

The failing function seems like maybe you didn't enable some legacy
proc stuff that OpenAFS may be depending upon
