I have not been able to get SCSI to work on a Tyan II motherboard since I have installed 2.4.x kernels on this machine. This worked with 2.2.x kernels. (I.e. RH 6.2) This is what I have tried. SCSI boards: IWill SCSI-3 controller Adaptec SCSI-2 - 2940 controller (currently installed, new and old driver) Kernel versions: 2.4.7-10 (from RedHat) 2.4.20 (tag version from kernel.org) The problem appears to be interrupt routing. The SCSI bus probing times-out during boot. This works fine when I use a Uni-processor kernel. (either version mentioned) This is a bummer since this server only has 166 Pentium processors. PS: I have tried compiling the kernel with various processor selections, down to 486, with no change in behavior. I don't see any messages regarding APIC stuff. Recommendations?
