Lou,
This has been a frustrating problem that has been around
since 2.2.6 . In that release both the sg driver and
the aha152x driver were changed. I was responsible for
the first change and the Juergen Fischer who maintains
the aha152x was _not_ responsible for the second change.
The only solution I know to this problem is to regress
the aha152x driver to what it was is 2.2.5 . There is a
copy of that driver at:

Naturally you will need to rebuild you kernel. If you
still have problems then contact me.
