So I installed Fedora Core 1, and tested with kernel 2.4.22(Fedora) and= =20 "vanilla" 2.4.24.

The scanner isn't recognized, and gets missing in=20 /proc/scsi/scsi. So I tried downgrading just the kernel to version 2.4.18(Redhat 7.3=20 kernel) and everything works! The kernel recognizes the scanner without= =20 complaining(it appears in /proc/scsi/scsi) and the sane-find-scanner an= d=20 scanimage utilities find and recognizes my scanner. After that, I downloaded two BIOS updates from Adaptec and applied them= =20 to my Adaptec card. But, even with these updates, everything is the sam= e=20 for kernels above 2.4.18. That said, IMHO there's something wrong in aic7xxx module(or scsi=20 subsystem) in kernel versions above 2.4.18.
