Hi Franck, Attached please find updated journalctl -b -0 log file. First, there are some ACPI - could they be sign of the problem? I reported this issue because I see it with clean, default KDE instal. I installed opensuse 42.3 and logged in - observing the systemd-coredump processes. I post updates, it behaves the same - observing the systemd-coredump processes. I did not start any application/process prior to dmesg or journalctl commands. As I have said it is all out of the box, fresh install + update. In fact, I installed 42.3 RC only to help with testing on a real HW. I have done exactly the same install on Thinkpad T470 (i5-7300 Kabylake) and it dos not suffer from the issue, nor from the ACPI errors. Thanks again for looking into this, Tomas
