Thanks for the bug report. I can see two immediate problems. The first problem isn't really related to this bug but you should fix it anyway. Your log is being flooded by crashes in 'onedrive'. If you don't need 'onedrive' then consider uninstalling it.
The second problem is these messages in your Xorg logs which might be related to this bug: [ 87005.338] [dix] EventToCore: Not implemented yet [ 87131.437] [dix] EventToCore: Not implemented yet [ 87283.009] [dix] EventToCore: Not implemented yet Next we would like to see a system log of the problem happening so please: 1. Reproduce the bug again such that the machine is unresponsive. 2. Wait 30 seconds. 3. Do a "hard reboot". 4. Run: journalctl -b-1 > prevboot.txt 5. Attach the resulting text file here. 6.

A few weeks ago, suspend stopped working properly: with an external monitor, the external monitor no longer registers the connection when waking from suspend.
