Yes, exactly... (hardware sucks) I mainly wanted to let other poeple
with the same hardware know about this workaround.

Since this is a real panic, and not a hang, I think this workaround just
hides the real problem which might be somewhere else.  I hope to have a
look what really goes wrong tomorrow.  I guess it's time to try firewire
debugging.

BTW. I haven't told you about the problem before because didn't want to
bother you with the problem until I could give you a proper error
report.
