These messages don't come from our drivers. They are either from ACPI or
from CPU-specific MCE. Search the web for "Running in modulated clock
mode" and you'll find several references to your problem.
You should check if you can find anything relevant in
/proc/acpi/thermal_zone. If temperature limits are too low, try
As for MCE, I don't know how you can change their threshold. Maybe it's
just a matter of improving the CPU cooling.
