Just a note: ACPI in 4.x is mostly a joke (I know, I did the backport).  All 
it really does is make sure the power button works as well as the timer and 
maybe simple CPU throttling.  The thermal stuff might work (fan control, 
etc.) but it's not guaranteed.  ACPI in 5.x is much more mature though it 
seems to have a problem on your particular machine.  Can you boot a 5.x 
kernel with ACPI enabled over a serial console to capture the dmesg to a log 
and e-mail it back?
