The arguments to key_alloc() changed with 2.6.29, but this was fixed only recently in the OpenAFS source - it wasn't fixed in the original patches for 2.6.29. I would guess that's the cause of the oops.
You might want to try current OpenAFS source or a 1.4.9 pre-release. Marc -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
