long delays while copying & aborted sbp2 commands

Hi all,
   It's been a while since I've been subscibed here. Linux 1394 has
been working well for me as much as I've been using it for only hard
drives. No real problems.

   I'm now setting up a new audio recording set up to replace my Win
XP Pro Tools setup. I'm using three 1394 drives hanging off of two
OHCI controllers. Everything is working, but periodically, which
copying files from one drive to another, I seem to get very, very long
delays where nothing is happening. No activity lights on any of the
drives and Gnome's progress bar has stopped.

   In dmesg I see the following:

I put the break in to show what happens. There are no blank lines in
dmesg. The first delay shows up with tags 33/34/35/36, and when the
copying resumes I don't get any more messages. Awhile later I get
another delay and I see the tags ef/f0/f1-f6. This happens a few more
times as you see.

What's going on here?

Anything I can do to make this work a bit better?

Original build up is FC2. The kernel is 2.6.11 based, custom built at
Stanford, but I believe that the 1394 stuff is whatver is shipped with
the kernel from Fedora.

Thanks in advance.

Cheers,
Mark
