I guess this patch makes panic on my notebook:

cpu0: <ACPI CPU (2 Cx states)> on acpi0
acpi_perf0: <ACPI CPU Frequency Control> on cpu0
acpi_perf0: failed in PERF_STATUS attach
device_attach: acpi_perf0 attach returned 6
panic: resource_list_add: resource entry is busy
KDB: enter: panic

...

How to fix that ?
