Another data point. I put the cyrix cpu on a more modern motherboard and it boots fine. That blows my theory that the problem is with the cyrix and 2.4 kernel. I was thinking maybe some cyrix specific workarounds needed to be set in the compile. My new theory is there is a problem with the new kernel, (.config flags?) and the motherboard chipset. I am attempting to switch processors to see if the problem goes away. Any ideas? Other suggestions? If I bugzilla this problem what categories should I use?
