A bug in the util-linux-2.12a-21 update package. This happened last
week. See:
http://www.redhat.com/archives/fedora-list/2005-March/msg06712.html
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=150775

Quick workaround: use the "udp" mount option.

This is supposed to have been fixed by the util-linux-2.12a-23 package,
released earlier this week:
http://download.fedora.redhat.com/pub/fedora/linux/core/updates/3/i386/util-linux-2.12a-23.i386.rpm
