Hi guys,
I’m still having some trouble with my new laptop, a Thinkpad L13 Yoga. One of them is, when waking up from suspend2RAM the network is sometimes dead. In this case, it always helps to just suspend and wake up again, so it is just a minor thingy, but it still bugs me.
I found the following lines in the journal whose timestamps fit to the wakeup event:
Nov 19 20:34:14 ThinkpadL13Yoga systemd-coredump[258147]: [🡕] Process 212695 (systemd-logind) of user 0 dumped core.
