SCSI Tape not detected in i586 variant of 2.2.5-22

Upgraded from Red Hat 5.2 to Red Hat 6.0 with the kernel
from kernel-2.2.5-22.i586.rpm. The SCSI tape drive (Exabyte
8500 on Adaptec 2940) was no longer detected by the kernel
during boot. Switching to the kernel in
kernel-2.2.5-22.i386.rpm appears to have fixed the problem.
The i386 variant of the kernel detects the SCSI tape drive.
that's odd. In both cases the st driver is compiled into the
kernel. Exactly how does it fail - does the device not show
up in /proc/scsi/scsi?
References to /dev/st0 produce the error "no such device" and the tape
drive does not appear in /proc/scsi/scsi. Other SCSI devices (hard
disk and CD-ROM) are detected properly. The SCSI tape driver _is_
listed in the link map for the kernel.
Out of curiousity, what happens if you try the i586 kernel
from Raw Hide
or compile your own i586 kernel from the same sources?
