When did this begin? Did you just upgrade something, new kernel, etc?

Not sure if this message is related to your CPU frequency stepping (I'm
getting similar ACPI messages when the fan kicks in: ACPI event unhandled:
thermal_zone TZ1 00000081 00000000)

If you delve into your ACPI configuration files you can define an action on
your message. Otherwise, just ignore it like I do and configure logrotate to
keep your log files down to a sensible size.
