Theoretically you can use a i8042 filter to filter out those special

event without a good reason. Can you share the output of "acpidump"?
Thanks, Armin Wolf
I've attached the dump. Not sure if it means anything but when i ran
the command i also got this error:
Table signature (0x4F324824) is invalid
Could not get ACPI table at index 29, AE_BAD_HEADER
This seems to be caused by an oddly named ACPI table ("$H20"). I will ask the
ACPICA guys if this check can be relaxed. Other than that this error is harmless.
It also seems that the ACPI code contains the necessary logic to submit an turbo mode
WMI event. I suspect that some settings have to be enabled first.
I also noticed some difference in the turbo behaviour on linux and
windows. On windows, making the WMI call increases my fan speed and
raises my CPU's throttling temperature to 100 C. The same increase in
fan speeds is observed in linux but the CPU's throttling temperature
is not affected. I don't have any thermal management daemons running
and the CPU scaling driver is intel_pstate, do you have any idea what
could be causing this difference?
The thermal control should be handled by thermald.

Thanks for looking into this!
