Edited the grub command, added i8042.reset=1 parameter, F10 to boot. Internal keyboard worked. 2. Repeated 1 above but when I typed as far as "i80" the internal keyboard stopped working. I completed the parameter with a USB keyboard, F10 to boot and unplugged the USB keyboard. Internal keyboard was working when I came to log in. 3. Updated boot parameters in Yast adding i8042.reset=1 parameter. 1st boot after when I used "e" to look at the grub command - OK. 2nd boot after when I pressed <Enter> to boot immediately - keyboard not working. 3rd boot again after when I used "e" to look at the grub command - OK. 4. Tried adding i8042.dumbkbd=1 - no good. 5. Tried adding i8042.nomux=1 - OK. 6. Tried with i8042.noloop=1 - OK (not using .nomux=1). 7. Added i8042.nomux=1 parameter to boot command using Yast, just to see what happened. Since then the keyboard worked on every boot even if I press <Enter> to boot immediately. On one occasion the built-in trackpad did not work until I plugged in a USB mouse and removed it. Trackpad then started working OK. The root partition is installed on an NVMe M2 drive (formatted ext4) with i7-10875H processor (16 threads). Running "top" I saw that 'rsyslogd' and 'systemd.journal' are each using 100% of a processor. In the past I have noticed that 'xz' has also done this. Maybe irrelevant, but odd. I shutdown the laptop and needed to use a long press on the power button to turn it off. After I restarted it, after the grub screen the login screen did not appear. Given this and the inexplicable failure of the built-in keyboard in 2 above I suspect a hardware error and will be contacting the supplier tomorrow. Can you put the bug report into a 'suspended' state until I have resolved any hardware issues? Many thanks for your help - I've learnt a lot!
