(NB: i'm not subscribed to -stable, please Cc me.)
The kernel causing this is not too recent, but the file in question
(nfs_vfsops.c) is at the most recent revision. I've got two of these
panics with the exact same picture, within 10 days. This last
coredump is still available for further examination. (The machine
where this happens usually runs xfsm, a graphical df tool. This
explains why it runs the statfs() calls quite more often than other
machines would do.)
