FWIW: This is a NULL function pointer that's trying to call a
function that hasn't been initialized, or has been explicitly
NULL'ed out.  Decoding the pointer values to find out what the
object are would probably go a long way toward knowing what's
going on.  Last time I saw one of these, it was the NFS lease
function.  He might also want to look for any function pointer
that takes 5 arguments; Linux threads is a likely suspect, in
that the thread mailboxes are at a fixed location, so he should
make sure to recompile any kernel modules when he compiles his
new kernel.

BTW: Good work on the patch, both you and Peter!
