Okay, this has happened repeatably on two Acer Altos boxes. Sorry to be so silly, but I can't think what else I can configure. The jumper on the disk is set to master, it is plugged into the primary using an ATA100 cable, the power is on :-) On the other dual CPU box (using older kernels), I could boot into a single CPU kernel on the machine, and the disks would work. Boot into a SMP kernel, no recognition of the bus in /proc/ide, and fdisk reports the other disks, but not those plugged into the cmd card. The cmd64x driver is compiled directly into the kernel, not loaded as a module. Any other suggestions? Where can I find more evidence?
