General Protection Fault in openafs, 2.6.25 and 2.6.26 kernels
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.
Any adivce? Thanks.
