Dear Linux folks,
On an ASRock E350M1 and a PS/2 keyboard connected, starting it with
`i8042.nopnp`, the PS/2 is detected and works fine. In this case I am
using Linux 4.10.
```
kernel: i8042: Probing ports directly.
kernel: serio: i8042 KBD port at 0x60,0x64 irq 1
kernel: serio: i8042 AUX port at 0x60,0x64 irq 12
kernel: mousedev: PS/2 mouse device common for all mice
```
Suspending and resuming the system, the PS/2 keyboard then doesn’t work
anymore. As a workaround a keyboard connected can be used.
Using PNP, that means ACPI, the keyboard also works after resume.
Is that by design? As I don’t see any i8042 messages in the log after
resume, I wonder, if the devices on the PS/2 controller should also be
probed during resume by the Linux kernel.
Kind regards,
Paul
