Hi,
I'm seeing something similar on my X395 since some weeks. I *think*
failure to suspend happens only after I've played a few large (HD) video
with mpv, maybe in chrome too. I've not tried to figure out a
reproducer.
When it happens, and the machine sits a the login prompt, I can still
interact with it for a couple of minutes before it freezes: type
commands, enter ddb,... I cannot switch back to X (either instant
freeze or panic) nor retry zzz. halt -p sometimes works, sometimes
unlock the pending supend (so the machine suspends, and powers itself
off shortly after resume).
Unfortunatly I've no idea what kind of resources to look for that
would be blocking the suspend path. Any clues of stuff I can run on
the console or in ddb next time this happens ?
