Hello,
I am running kernel-default-4.4.27-2 from Leap 42.2 repo using Leap 42.2
and see the following message repeating every five seconds. It starts at boot.
The same hardware worked well on Leap 42.1 (kernel 4.1.x).

I don't know how It could be related, but other parts of the system also
non-operational. For instance, i210 intel networking don't work.
But OS itself seems to be booted and I can login using getty.
