Both of them don't work properly.

With `i8042.dumbkbd`, there seem to have some interrupts but with no data. After typing the keyboard, there are lots of `interrupt 1, without any data` logs in the output of `dmesg`.

Is this a Rembrandt system?  If so I would expect the general solution Chuanhong 
 is making for https://lore.kernel.org/linux-acpi/20220630022317.15734-1-gch981213@gmail.com/ to fix this too.

Here is the v6 of that patch: https://lore.kernel.org/linux-acpi/20220712020058.90374-1-gch981213@gmail.com/T/#u

Please have a try and report back.

Yes, this patch does fix it.

This patch broke my laptop's built-in keyboard. My laptop is a GPD Win Max2 with AMD 6800U.

After upgrading kernel 5.19.10 from 5.19.9, the built-in keyboard of GPD Win Max2 does not work.
 
I revert the commit(37c81d9f1d1b1458894454efcb857f6a769b6bc4) and rebuilt the kernel. The built-in keyboard of my laptop works again.

That's really unfortunate to hear.  We may need to revisit the heuristic.  Can you please do me a favor and open a new bug report, attach the following, and CC me:
1) dmesg log from 5.19.9
2) dmesg log from 5.19.10
3) acpidump
