Thanks alot :) - I'm actually building it now on 2.6.22-rc6.

However there seems to be something within ipr.c that doesn't compile right:

==========================================================
Error Msg:
==========================================================
drivers/scsi/ipr.c: In function ‘__ipr_eh_dev_reset’:
drivers/scsi/ipr.c:3955: warning: passing argument 4 of ‘ata_do_eh’ from

make[1]: Leaving directory `/usr/src/linux-2.6.22-rc6'
make: *** [debian/stamp-build-kernel] Error 2
==========================================================

I just removed the ipr module since I'm not going to use it, but maybe
I'm doing something wrong since I'm usng the debian build process (?),
anyways I downloaded 2.6.22-rc6 from testing on kernel.org, so that
should atleast be right.

Thanks for getting back to me, I will report back how well my 3531-based
controller fares...

Kind regards,
Stefan
