    Intel NUC D54250WYK ACPI (DSDT) firmware issue

    Todor

      Hello,

       

      We have a D54250WYK HSW NUC running Linux. We noticed that the NUC advertises to the kernel the following PS/2 devices via the ACPI tables (DSDT).

       

      PNP0303(IBM Enhanced (101/102-key, PS/2 mouse support))

      PNP030B(Reserved by Microsoft)

      PNP0F03(Microsoft PS/2-style Mouse)

      PNP0F13(PS/2 Port for PS/2-style Mice)

       

      As a result the kernel tries to load the serial controller driver (i8042) multiple times which affects our boot time.

      Obviously there is no PS/2 controller and we end up with messages like these:

       

      i8042: PNP: No PS/2 controller found. Probing ports directly.

      i8042: PNP: No PS/2 controller found. Probing ports directly.

       

      Is this intentional or a firmware issue?
