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
kernel: [Hardware Error]: section_type: Firmware Error Record Reference
kernel: [Hardware Error]: Firmware Error Record Type: SOC Firmware
Error Record Type2
kernel: [Hardware Error]: Revision: 2
kernel: [Hardware Error]: Record Identifier:
8f87f311-c998-4d9e-a0c4-6065518c4f6d
kernel: [Hardware Error]: 00000000: 0100a306 00000280 ca5824d3
000003ab .........$X.....
[…]
```

How can I decode that error to understand what happened?


Kind regards,

Paul

Dell or Intel should be able to provide that information, although
getting them to do so may be difficult.
