[ale] multi-processor vs. Tape Drive

[stalax at earthlink.net (James McFarland)]

I hope someone on this list can point me in the right direction.

I am trying to turn an old dual P3  server into a basic fileserver.  I added an adaptec 2200s Dual Chanel SCSI Raid Controller.  To Chanel  0 I connected 3 drives for a RAID 5.  To Chanel  1 I connected an external Tape drive.  I then installed Fedora Core 3.

When I use the SMP Kernel, the system cannot find the Tape Drive (lsmod shows st isn't loaded).  When I use the single processor kernel, It finds the Tape drive just fine, but I get only one processor.  In either case, it sees the RAID array just fine.

I have updated the BIOS on both the motherboard & the SCSI card.  Removing the RAID array or changing SCSI channels makes no difference.

It seems to me that there is a difference in the Kernel configuration somewhere.  However, my kernel knowledge is limited at best & my initial attempts to locate a meaningful difference have been unsuccessful.

I am running the basic Kernels installed with Core 3 (2.6.11-1.14_FC3).

If anyone can offer a suggestion as to where I should look in my system's configuration, or direct me towards an appropriate net resource I'd really appreciate it.
