Aside from Andrew's last request, I see that a very similar issue was discussed on LP# 1881109 [0] but, at that time, tests with a later kernel didn't reproduce the issue.
You're running 5.4.0-71 there. Have you been able to reproduce this using either 5.4.0-73 or 5.4.0-74 (the latter in Proposed, only)?
Greetings!
