Well whatever bug it is, it's in Linus's tree now. Happens for me too.

I traced the failure down as far as acpi_processor_get_performance_info(),
where it's failing here:

status = acpi_get_handle(pr->handle, "_PCT", &handle);
if (ACPI_FAILURE(status)) {
ACPI_DEBUG_PRINT((ACPI_DB_INFO,
"ACPI-based processor performance control unavailable\n"));
return_VALUE(-ENODEV);
}
