Hi
My laptop will not resume after suspend to RAM (low battery, or lid closed etc.). From user observation only, suspend seems to work normally, then resume “tries” (there’s a time when it looks as if it will work as previously) but then it reboots instead. This started after updates ~21st June. Further updates have been applied without success. The journal records a reboot (literally “-- Reboot --”) after lines indicating the system was put into sleep mode (e.g. last line before the reboot starts “systemd-sleep[16973]: preparing boot-loader: selecting entry openSUSE Tumbleweed”), and lastlog indicates a resume starts and then the system shuts down:

Suspend/resume has normally worked without fail, since this (Dell XPS13) laptop was first installed in 2015. Any ideas?
