Public bug reported:
Kernel linux-image-7.0.0-31-generic was last working. Since then with every
kernel USB keyboard is not recognized. This happens only when booting from NVME
and not from Sata SSD. This is specific to AMD system (here MSI B450 Mortar
Max). Mouse from the same KVM works fine.
Typing with screen keyboard and mouse.
