i8042_init: PS/2 mouse not detected with ACPIPnP/PnPBIOS

2020-10-07 Thread Paul Menzel

Dear Linux folks,


On the Asus F2A85-M PRO Linux 5.9-rc8 (and previous versions) does not 
recognize a plugged in PS/2 mouse using the Plug & Play method. The PS/2 
keyboard is detected fine, and using `i8042.nopnp`, the PS/2 mouse also 
works.

But, the DSDT includes the “mouse device”. From

we get

}

and the identifiers PNP0F03 and PNP0F13 are both listed in the array 
`pnp_aux_devids[]`. But adding print statements to 
`i8042_pnp_aux_probe()`, I do not see them, so the function does not 
seem to be called.


Hints for further debugging are much appreciated.
