AceLan Kao,
     Going the HP support route we all know will be extremely painful, if, I 
can convince their support to forward my query along to the right people.

Is there no method to debug or expose the reason for the failed PPM init and/or 
what the GPE17 triggers are called from?
I am assuming if I go back to Windows 11, the cpu is calm and the interrupts 
are not happening.
I am also assuming the issue to be that whatever the triggers are, the response 
is not expect or not happening, therefore the triggers continue.

I found a similar bug that mentions the unloading the ucsi_acpi module.

Bug 217076 - Charging causes high CPU usage on LG Gram laptops series Z90Q

I would like some help identifying if it is similar in nature since that
patch was very specific to those LG models.

Title:
  kacpi_notify high cpu on interrupt gpe17

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Picked up a HP laptop during July sales, and found the CPU soars to 80+ with 
kacpi_notify hitting GPE17.
  I would like some help finding the cause.  Google searches were vague about 
masking the interrupt which did NOT help.  If we can find what is calling the 
interrupts maybe we can better document a solution.
