Amusingly enough, I just got one of these today.
(AMD Athlon(tm) 64 X2 Dual Core Processor 4200+)
Mine also seems to stick at 1ghz on both cores instead of ramping up
to 2.2ghz (as the cpus are able to).
It looks to me like a bug in the 'ondemand' cpu govener...
If I simply change to performance:
echo "performance" > /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
It goes to 2.2 and stays there. ondemand seems to never raise from the
lowest possible speed here.
tried that, changing the governor doesn't seem to fix the issue on my
machine.
For reference this is a Shuttle SN95G5V3, motherboard is a Shuttle FN95.
I haven't been able to dig up any known issues with that hardware and it
used to work just fine.
