Shutdown Issue
I get the following error when I try to shut down my laptop:
So I have to forcefully shut it down with the power button.
OS: Ubuntu 18.04.3
Laptop: ThinkPad E585
Graphics Card: AMD Raven
(By the way, in the screenshot, the numbers in brackets in both the lines keep changing every time. For example, the second number changes to 375 and 376 as well.)
Linked Suspend Issue
In addition, I am not able to suspend my laptop as well. It sort of tries to suspend but after a few seconds lock screen comes up so I have forcefully shut down my laptop. I think this suspend issue is connected with the above shutdown issue since they both appeared around the same time.
Background
Originally, I had issue with waking up my laptop after suspension (my laptop screen would go black on wake up). I had tried to resolve it but I couldn't and now recently the above shutdown and suspend issues have appeared. I am not sure if the wake-up issue is linked with shutdown/suspend issues.
