(In reply to Thomas Schäfer from comment #2)
The kernel versions with the problem are:

4.11.5-1 and 4.11.6-1, probably also some earlier versions, but not before

Was the last working one already 4.11.x, or 4.10.x? You can check the zypper
installation history from the log.

At the moment I can't reset the device, but I can provide the message a
older kernel now shows:

[ 4.165943] i8042: Can't read CTR while initializing i8042
[ 4.166074] i8042: probe of i8042 failed with error -5

Thsee messages can be ignored. The Baytrail / Cherrytrail devices have no
i8042 serial connection so the kernel used to show this error message in the
The recent kernels don't probe the i8042 in a fixed way but rely on ACPI setup,
hence the message disappeared.

A other possibility would be a hardware defect, but the device is quite new.

You can try the older kernel from my repo, e.g. OBS home:tiwai:kernel:4.10. If
it works, we still have a hope.

If you get a working kernel again, please get dmesg output on both working and
non-working cases.

BTW, is this only about the built-in keyboard, or doesnt even USB keyboard
