I have a machine running the cyclades YeP-16. Everything worked fine with
2.0.33 kernel. I swapped out the Magitronics motherboard that was in it
for a HOT-601 (said to be the BEST P5 motherboard by just about every
motherboard survey on the net), and the cyclades does the exact same
thing. I upgraded the kernel to 2.0.34, and same thing.

I can load the module, but as soon as I try to access one of the serial
devices it locks.
