Dear folks,
I have tried cmd649 ATA pci cards; they work great with single CPU
kernels, not at all with SMP kernels. The SMP kernel just does not make
an entry in /proc/ide. Some details are in my post on 13 Feb, with
subject: cmd649 ok 1 cpu, 2 cpus, not working. I would appreciate any
pointers that may lead to getting them working.
So if this is not a common problem, does _anyone_ use ATA cards with SMP
boxes? If so, which ones work? HPT?

LOL, I had the same question asked to me by CMD and probed to them it
works. Obviously you have not configured something correct :-/

Thanks for your reply, Andre.
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? Willing to try
anything!
