Public bug reported:
```
$ lsb_release -rd
Description: Ubuntu Focal Fossa (development branch)
Release: 20.04
```
- 64-bit
- Gnome 3.34.2
- X11
This error message triggered while my desktop computer booted up, so I
expected it to boot up without an issue.
I found where `Bad rss-counter state` first appears in my `journalctl`
log, so I pasted every log during the time 0228 hours. there were no
logs during 0227 hours.
