Subject: What to do with `BERT: Error records from previous boot`?

Dear Linux folks,

On the Intel Tiger Lake Dell XPS 13 9310 Linux 5.9.9 from Debian 
sid/unstable logged the messages below. Please find the whole log in the 
Linux bug tracker [1].

```

How can I decode that error to understand what happened?

Kind regards,
