Looks like TLP was installed on my laptop at initial installation time. rpm -qa | grep -i tlp tlp-1.0-1.2.noarch tlp-rdw-1.0-1.2.noarch The latest openSUSE Tumbleed snapshot switched to 4.14 kernel - I got the same issue with that too on first boot. The bug report in openSUSE's bugzilla contains the /var/log/messages for that first boot with 4.14.
