Hi.
I'm getting this one. The mount.nfs call is being called by the
autofs-daemon.
It is not directly reproducible, but happens around once a day on a single
node on a 48 node cluster.
I reported it to the NFS-guys on a .22 kernel, and was directed to the
fsdevel list(CC'ed again) back then. Now the problem is reproduces on
.26-rc4
