Right, I'm talking with SuSE at the moment, they want me to try
changing /sys/block/sdX/device/retries (from 5 to 10)  They also want
a tcpdump, but I've told them that will be in the gigabytes of size.
I gave them the tcpdump summary from above...

Once I've done experimenting with retries and send the details back to
SuSE I'll try your suggestions (-:

*phew* so busy... so much to do!

At the moment I'm using a development server for testing (it fails
just like the production servers do with the distro supplied open-
iscsi drivers), so I'm not worried if your tarball nukes the server.

Thanks again
