Panic on IBMMCA SCSI driver with 2.6.30

No, this isn't a joke. I actually still have an IBM 9595, and I've been
running 2.4 on it all this time. A friend of mine tried to upgrade one
to 2.6 and couldn't get it to boot. I managed to get a bit of serial
console output of the error it is throwing. I don't speak SCSI very
well, so I'm hoping that you guys might have some insight.
I added all the debug output that I could find. I actually have a tiny
compile fix or two for the debug code that I'll send along in a bit.
I'm sure the other 3 MCA users will appreciate it.
Alan and James, you touched the file last, so you *must* be experts on it, right? ;)
