I bought an Adaptec SATA controller to add some backups to a system that already had an Adaptec SCSI controller. They're both recognized as AIC7xxx, but the second one is somehow blocked.
I can access the on-controller configuration stuff during BIOS startup, and the drives appear good. I just cannot get things working with the Linux kernel. I think this is the relevant part of dmesg output. Notice the message about "Unable to reserve mem region". In case I'm wrong, I've attached the whole thing too. ...
