OS: Ubuntu 21.10 x86_64 DE: GNOME 40.5 CPU: AMD Ryzen 7 5700U GPU: AMD ATI 03:00.0 Lucienne kernel: 5.13.0-20-generic

Similar question is here some function buttons not recognised (even at scancode level) after resume from sleep

partial output of

sudo dmesg | grep i8042


[    0.683130] i8042: PNP: PS/2 Controller [PNP030b:PS2K] at 0x60,0x64 irq 1

[  142.744956] input: AT Translated Set 2 keyboard as /devices/platform/i8042/serio0/input/input13

and after every suspend and resume cycle it continues to add keyboards

[   19.887413] atkbd serio0: Spurious ACK on isa0060/serio0. Some program might be trying to access hardware directly.

A strange thing is that dot button doesn't work

xev doesn't react on the key press, brightness controll (fn+F4, fn+F5) too

I have tried everything from this list to configure grub

#i8042.nopnp noacpi nolapic atkbd.reset
#i8042.nopnp i8042.dumbkbd

Nothing helped, sometimes the keyboard stopped responding and sometimes caps-lock indicator stopped indicating

But nothing helped to activate dot and functional buttons

Please help me, I've spend 2 full days trying to configure the suspend mode

Have the same problem

It looks like it is fixed in newer versions of kernel I don't know though how to fix this issue without updating the kernel manually
