Duh, 3GHz SMP, I doubt very much its a VIA c3, ignore last email. 8-)
I'll change my guess to dual P4. I'm surprised that any of the
cpufreq drivers do anything on desktop p4's (other than p4-clockmod
which still does comparatively little). My cloudy 'not quite
firing on all cylinders at 3am' memory is recalling some patches that
would prevent triggering these messages not so long ago, but I'm
fairly certain they should've been in that Fedora kernel you're running.
Most odd.
Can you paste the whole dmesg please?
Dave
