But it did, actually. The "trying to register..." is a pr_debug call for
example.

this is cpufreq_register_driver()

this is acpi_processor_register_performance called by powernow_k8_cpu_init_acpi

Yep, cool. This tells us that it is -EIO which means
that acpi_processor_register_performance returns -EIO
after trying acpi_processor_get_performance_info. The "..
performance control unavailable" message above tells us that
acpi_processor_get_performance_info fails when trying to get the _PCT
handle.

So, to recheck: are you sure your "Cool'n'quiet" option in the BIOS is
enabled? If not, please enable it and retest.

Thanks.
