BUG at net/sunrpc/svc_xprt.c:921

From: Tom Horsley

I noticed some previous messages with this subject, but the
walkback I'm getting doesn't match exactly the ones shown
in the threads I saw, so I figured I'd send this in.

This happens on both my Fedora 18 and Fedora 17 partitions
when mounting filesystems from very old servers that
need the proto=udp option to talk.

The redhat bugzilla is here:

https://bugzilla.redhat.com/show_bug.cgi?id=908451

There is a photo of the walkback in that bugzilla:
