Hi Lovekesh,

thanks for the quick reply.

I tested with only i8042.nomux=1 (without i8042.reset). Keyboard and
touchpad work on both a warm reboot and a cold boot, so the reset
parameter is not needed.

/proc/cmdline during the test:
  BOOT_IMAGE=/boot/vmlinuz-7.0.0-31-generic ... ro quiet splash
i8042.nomux=1

Happy to test a patch on this machine once you have one.

Great! I'll just submit the patch upstream directly within the hour.
You could test it and reply with a Tested-by tag on it.

Regards,
Lovekesh
