James/Andrew,
The 2200 firmware doesn't support the MS IOCB interface the driver
uses to issue CT commands to the SNS. Basically, I had to
forward-port some code from the 6.x driver to get the SNS calls
to go through. I've had several machines (mixture of 2200s/
2300s/others with loop and fabric connections) running with this
patch for the past few days.
Please apply.
Regards,
Andrew Vasquez

I applied your patch to 2.6.2-rc1 and tested it on my ppc64 box. Looks
like its not happy :) Maybe a 64bit or big endian issue?

Hmm, I think I know what the problem is. Could you try the attached
small patch. The handles that get passed down to the firmware should
be opaque. Unfortuantely when using RIO mode 3 (as is done with the
2100 and 2200s) the handle is truncated down from 32bits to 16bits.
Looks like I need to add the ppc64 machine to my test ring. BTW: any
quick doc-pointers or suggestions on how to get 2.6 running on a ppc64
machine.

Gave it a go but it still seems to have problems (see below).

Current -mm should run on everything. Linus tree is missing a one line
fix in the pci probe code, we still need to convince him to take it.
Let me know if you have any problems.
