I was searching why suspend is not working anymore with 5.0.0-23 for me and found this similar bug.
Sometimes it is coming up again after trying, sometimes it freezes. I tried the echo cmd from #20, no difference for me. But with 4.15.0-55-generic it works for me (unlike the initial report if i understood it correctly) I have a Lenovo P52, let me know if you also want a full report. root@p52:~# lsb_release -rd Description: Ubuntu 18.04.3 LTS Release: 18.04 dmesg from 5.0.0-23 [ 47.473308] wlan0: Limiting TX power to 30 (30 - 0) dBm as advertised by cc:50:0a:d0:d6:fb [ 104.073889] PM: suspend entry (deep) [ 104.073890] PM: Syncing filesystems ... done.

It immediately wakes up after going through all the usual steps of turning off the screens, USB devices etc. I'm using the UI to suspend by left-clicking and holding the power off button until it turns into a pause button, and then I left-click that button. The laptop is docked with two monitors connected and the lid is open (although the laptop screen is not used) when I attempt to suspend it. This used to work until recently. BIOS has not been touched or upgraded. Log excerpt: ...
