Bug Description
My laptop's CPU temps are not read by the kernel. This also causes the thermal trip points to not be triggered, makes the laptop overheat, and causes the fan to run constantly. This has been present in every kernel version. The cause is a buggy dsdt. I have used a custom dsdt to fix this. The dsdt bug is referenced here for a different model: https:/

I will add that my dsdt was compiled by Nvidia with the MSFT compiler which is not ACPI compliant. The IASL compiler makes 1130 optimizations on top of the errors I fixed.
