Public bug reported:

In one of the recent updates suspend is now sometimes broken on the
Lenovo T460s. I've updated the BIOS to the latest but the problem
remains. Sometimes suspend works correctly and other times it just fails
completely. Before the BIOS update it seemed to be stuck on resume and
needed to be forced to reset. After the BIOS update it just seems to
turn off by itself on resume.

I haven't been able to find anything relevant in the logs. They just
show normal suspend and then a boot instead of resume. I'm assuming a
kernel regression but there's also been some systemd updates recently.
