Recently I upgraded to RH 6.2. When I did the cyclades boards (Cyclom-y series) stopped working. As soon as the kernel tried to load the drivers either directly in the kernel or through a module, the entire system would lock-up. I tried everything to get it to work. Finally, I simply installed 6.2 (with the driver as a module of course) and did not modprobe it. Then I downloaded kernel 2.2.16 from kernel.org and everything works beautifully. I am contacting cyclades to inform them of the problem. It worked fine on RH 5.2, but never worked on 6.0,6.1, or 6.2 (there were separate issues on 6.0 and 6.1 from this one).
6.2 errata kernel is 2.2.16 so should be fine. If not re-open
