I tested with only i8042.nomux=3D1 (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=3D/boot/vmlinuz-7.0.0-31-generic ... ro quiet splash i8042.nomux=3D1 Happy to test a patch on this machine once you have one.
