All, I performed this morning an upgrade from TW 20171116 to the latest TW 20171125 on my ThinkPad T520. After beeing on TW for 9 month, this was the first really bad experience: The system froze during the installation of virtualbox-host-kmp-default|5.1.30_k4.13.12_1-4.1 Desktop (Plasma) was not reacting at all, needed to switch off. After next boot, zypper dup was performed again (w/o problems), and reboot afterwards. After login to KDE the screen remained black, just the cursor could be moved. Further on, no response, Session could not be killed with CRTL-ALT-Backspace Hard switch off again. Reboot and login with a different user. System was extremely sluggish with complete unresponsiveness (Gedenkminute) in between. Booting into an older snapshot finally saved me. Any ideas what this could be?
