Does it also happen with USB?
It seems that the firewire portion of the Acomdata enclosure is Initio,
like this one. So, unless they changed something, or the firmware is
different, I don't know. Can you test the Acomdata one again?
There seem to be no relevant changes in sd(4) since 3.0, perhaps some
higher layer was changed.
Also, how is/was the reliability and performance of the FreeBSD/NetBSD
firewire implementation? I've been having a horrible time with
fwip(4). Just wondering if getting a combo enclosure is worth it
if it's only going to be used on NetBSD.
