Over the past month, Ubuntu 18.04 occasionally freezes. My mouse will be free but I can't click on anything or even use Alt+F2 for a command. I usually follow these directions to restart my system with the REISUB method (and I've also changed the permissions the way the user described). Whenever I rebooted the system I didn't look at the crash report but today I opened var/crash and found linux-image-5.4.0-47-generic.34291.crash that contained the following:

ProblemType: KernelOops

I'm running Ubuntu 18.04.5.

I'm not sure where to go from here so any help in the right direction would be much appreciated.

    I'd suggest filing that crash report via ubuntu-bug /var/crash/linux-image-5.4.0-47-generic.34291.crash . You can refer to https://help.ubuntu.com/community/ReportingBugs for more details. – guiverc Sep 29 '20 at 05:59
  • I've done a clean install because the crashes were becoming worse. I still have the crash report. But it looks like ubuntu-bug logs local system information. Is there any way I can still log this? Fwiw, I always reported the bug through the gui pop-up. – VerboseOaf Oct 03 '20 at 23:58
