Same for me at the beginning.
I tracked two of the HP problems (wrong temperature, wrong _PPC value)
down to wrong EC reads -> BIOS issue.
Someone (this is the guy who actually solved this) reported that
unloading psmouse helps. When I saw this report confirmed by other
people a .shutdown workaround was easy and got also confirmed working...
And now it even makes a bit sense...
There is a little microprocessor (Embedded Controller) pre-processing
sensor or other data which gets accessed via ACPI. This one also access
mouse/keyboard hardware (described a bit in ACPI specs).
Yes, I am aware that KBC is usually emulated by EC chip nowadays, what
does not really makes sense to me is how crazy the firmware is.
...
FYI:
You might stumble again over the EC in future...
I saw reports where mouse jittering or similar bugs where fixed in
drivers/acpi/ec.c
If trying ec_intr=0 boot param, not loading any ACPI modules or the big
hammer: acpi=off helps to solve mouse or keyboard problems it's probably
Embedded Controller related (which might need a fix in ec.c, AML or EC
BIOS code (in this case we seem to have the latter problem :) )...).
Yep, seen that, except for AML workarounds. Do you have any examples?
Although there seem to be lees complaints about mice jittering
nowadays... Or maybe they simply got tired of complaining ;)
