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?
