Sorry, did you miss the part about umount not  un-mounting, nor will force
option correct it, requiring a reboot as only way for it to recover, this
does _NOT_ happen with my freebsd desktop, if i pull the ethernet, go have a
coffee, come back plug it in, it reconnects within a very short time, my
friend who uses fedora 12 on her notebook, could drop out from the back
yard, but when she comes in close and wifi re logs in, she also can browse
nfs shares, its only ubuntu that wont.
