Are you claiming that after only a short and light amount of usage, you
run into problems? We are getting a number of problem reports with
recent ieee1394 versions with writing *large* amounts of data at a time.
A previous message from Larry asserts that it is failing with writing
large files.

when you claim used successfully, was that on Linux, and if so, what
type of device?

I dunno if that could be a source of error, but I would elminitate if
possible just to reduce the number of points of failure.

Have you tested with an older kernel, say perhaps 2.4.19?

These errors are not the same as reported by others in the thread
"Problem when writing large amount of data to an external firewire hard
disk."

Anyone know what kernel component is generating these errors? fs?

No errors from sbp2 regarding aborted comands and resets?

It is really in your best interest to cc the mailing list, however, to
leverage the most exposure and potential feedback. Therefore, I am
returning this to the list.

I hope to spend some time this week attempting to reproduce some of the
errors people have been reporting lately with new versions of
ieee1394/sbp2.
