I don't think it's likely that it's a linux kernel issue. If you want
something to try, you can try applying these two patches:

http://git.openafs.org/?p=openafs.git;a=commitdiff_plain;h=910f3d4cbba4cd78a8e6afa0b32e37ed7f292d18
http://git.openafs.org/?p=openafs.git;a=commitdiff_plain;h=35835af9bb85b358e4bdd11113b637ac0e52c56b

Those fix what may be a similar issue, but I'm not really sure if it's
the same thing as here. If that doesn't do it (it's good that you have a
reliable way of reproducing this), we'll need to look more closely at
the core (if you don't want to provide it since it probably contains
file data, instructions can probably be provided, though it's a lot more
detailed than what we've done so far). Or we can proably go the route of
giving you debug patches, but I'm not quite sure what to add quite yet.
