This seems to be a kernel/firmware issue, but the attached logs do not reveal much information when it occurs. I'll suggest you to:
1. try to capture the log with `apport` after the symptom happens again. If you're not the reporter, file a new bug instead. 2. please try new kernel from Focal or mainline[1], and/or linux- firmware package.
