I do not have any other cards, so not easily.  The above errors do not seem
necessarily hang or crash the computer.  I currently have messages full of
those messages, but the computer is still ok and firewire works (copying
large amount of data from firewire to ata disk - two crashes during this
300G copy).  I think there is an improvement though, as I now get a crash
instead of the computer hanging up.  I enabled crash dumps.
