`umount` doesn't work with VIA FireWire-card (and fwe), while transferring seems to work now
(did not with RELENG_5 some months ago)
When I use two TexasInstruments based FW-cards and want to umount a NFS-share it works as
expected, but when I replace one TI based card with a VIA (Fire II) umount doesn't finish
on the the client machine.
Same behaviour with two VIA cards, umount doesn't return to CLI on the client, but when I
interrupt the command (with Ctrl-C) the NFS-share actually got umounted, I also can remount
the same share (even with different parameters) without problems!
