   Hmmm. There isn't an architectural problem - that's what I fixed, but
I only have two Cyclades units here, so I've not been able to test a
configuration of 3 or more. It _should_ work, however. Do the probe messages
match the actual board configuration? Is it possible that there is an IRQ
conflict in your machine with irq15 (which is often assigned to a secondary
IDE bus, for example)?
