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].

```
kernel: BERT: Error records from previous boot:
kernel: [Hardware Error]: event severity: fatal
kernel: [Hardware Error]:  Error 0, type: fatal

```

How can I decode that error to understand what happened?


Kind regards,

Paul
