Didn't test but I did bisecting and after reverting commits:
e8363f332757ac22395fb120cc33b3262f9ee26c
and the main problematic one:
commit 0a6139027f3986162233adc17285151e78b39cac

ACPI: Thermal issues on HP nx6325
The previous reference counting scheme to enable power resources
got confused when multiple devices were present that might
repeatedly enable or disable the resource and throw off the count.
The new code simply lists the referencing devices which
are requesting the resource to be enabled. When there are none,
then it is off.
