IDE0/Slave Detection Fails in 2.4.x(2.4.4, 2.4.5, and 2.4.5-ac18 tested)

I am having a problem where the 2.4.x(2.4.4, and 2.4.5, and 2.4.5-ac18) kernel does not detect the IDE0/primary slave device. If I put a third drive in the system as IDE1/secondary master then that is detected. However
the IDE0/primary slave is never detected.

Using the 2.2.19 kernel the IDE0/primary slave device IS detected properly. This
can be seen below in the 2.2.19 Kernel Init Messages.

Below is some more detailed info.

Just an update: I have now tested it with the 2.4.6 kernel and the problem

persists :(

I failed to mention in the previous email that the machine is an 2 processor SMP machine.
