I think we've seen another report or two, but it's always been hard to
reproduce. That said, with the specifics you've offered about the kernel
version that introduced the issue, we've got a couple folks trying to
reproduce in a controlled environment.
In the meantime, could you post an (openafs) config.log from one of the
affected systems? It's pretty long, so maybe as an attachment for
mail to firstname.lastname@example.org is best.
