I got a regression when updated from 2.6.27-rc1 ro 2.6.27-rc2. The noticeable symptom is the powernow-k8 driver stopped working because the call to acpi_processor_register_performance() is returning -EINVAL.
Digging into the code a bit more, that's occurring because acpi_processor_ppc_status is not set. That should be set in acpi_processor_init(), but that function is failing to register the ACPI processor driver.
I've dug through the code and can't see why that call would fail. It doesn't look like there were any changes between 2.6.27-rc1 and 2.6.27-rc2, but I may have missed something.
Any advice or suggestions in debugging this appreciated.
