Thanks for the suggestion. Unfortunately, it does not seem to have been
effective. I removed the sbp2 module, reinserted it with max_speed=1
(this is still in the 2.6-test9 kernel), mounted and umounted /dev/sda2
to make sure everything was detected properly, and now I'm running
dosfsck on /dev/sda2 (a vfat partition I created to share data with that
other operating system) because of your note above and Daniel's
suggestion.

I thought I'd test with that partition because it's smaller and I'm
scared of using --rebuild-tree on the reiserfs partition. Luckily
neither of these partitions store valuable data as this is a backup
drive, so as long as the to-be-backed-up machines don't die and I don't
hose the drive itself somehow, I'm fine.

Having done all that, I'm getting the same read errors, and, strangely
enough, they're coming every thirty seconds (at least as accounted for
in the log):

    Nov 1 09:51:03 host kernel: ieee1394: sbp2: aborting sbp2 command
    Nov 1 09:51:03 host kernel: Read (10) 00 13 ca e8 8d 00 00 fc 00

    Nov 1 09:52:03 host kernel: Read (10) 00 13 ca eb 8d 00 00 fc 00

    (and so on)

I haven't tried writing yet, let me know if I should (in order to
provide a report).

Thoughts? Is there a bug somewhere in here that I can report?

Take care,

    John L. Clark
