Hello,
I have ASUS Zenbook 14 UM425UA (Ryzen 5 5500U + 16GB RAM version), but builtin keyboard doesn't work in both GDM and Gnome session (both X11 and Wayland) after cold power on, but works properly after reboot. GRUB menu works properly all the time. During problematic boots I see "Can't read CTR while initializing i8042" kernel error. I tried tricks with ignore "Asus WMI hotkeys" and blacklist Intel Virtual Button driver (this model has AMD APU however), but nothing seems to work. I tried to run Ubuntu 20.04 (HWE enabled), Ubuntu 20.10, Ubuntu 21.04 and Fedora 33, however all distributions have the same problem. I tried Kernel 5.11.3 and 5.12.0rc2 for Ubuntu kernel PPA without success too. I don't have options related to keyboard in UEFI and whole UEFI is very basic. ASUS didn't provide newer UEFI yet. Touchpad works properly all the time. Did you have similar problems with your laptops?
BTW. Hibernation doesn't work too even on kernel 5.11+ (this kernel has AMD SoC PMC driver), but this is a topic for another thread. Keyboard is more problematic from my point of view.
Best regards,
Patryk
