I'm about to submit a general endinaess patch tot he ieee1394 guys.

The problem is that you need different combinations of swapping for
different OHCI implementations, because the standard didn't specify a few
things it should have.

 I've been using 2 45 gig firewire drives using LVM
and XFS for months now.

I've been using a cd-rw firewire drive for about 3 days now, too.

Errr, this is pretty easy to fix.

In fact, it's what my patch fixes.

You can say whether you want the following swapped  or not (in any
combination, they are just flags)

1. selfid handling
2. reading
3. writing

Pismo needs 2 and 3 to work right.
Other OHCI on PPC (TI) need 1, 2, and 3.
Your titanium probably needs 2 and 3, since i believe it's based on the
uninorth, just a newer revision, right?

It'll be on the 1394 list in about 10 minutes.
