On B550M Steel legend + Ryzen 5600G i get the same wrong keyboard behavior on every boot.
When i want to select between ubuntu and windows the only option I can select are the first or the last because up and down arrows seems to work couple times at on press.
Also when I switch to command mode, there is no way to write anything, because when i pres for example wtf i get wwwwwwwwwtttttttttttttfffffffffff.
Keyboard is plugged to usb2 next to ps2 port.
What can I do to fix this ?
