Problem with FC3 on a via epia

[Rob Sonke]

Hello,

On my own server, I always runned FC2 without any problems. Now I 
installed FC3 and it's very unstable! Sometimes he runs for a few hours 
but sometimes he crashes after only a few minutes. And in the syslog I 
found this a several times:

Warning: CPU frequency out of sync: cpufreq and timing core thinks of 
399000, is 798000 kHz.

It's a Via Epia board with the cyrix 800 cpu. I didn't overclock anything.

Anybody who recognizes this or has the same problems?

Rob
