I get the following errors during boot (Ubuntu 22.04) in my kern.log:

```auto

```

I see from this post ([BIOS bug: `_TZ.ETMD` missing in ACPI tables](http://community.frame.work/t/bios-bug-tz-etmd-missing-in-acpi-tables/17653)) that this may related to thermal issues (although the last responses there are 2 years old).

Now this possible thermal connection is interesting because I’ve been having problems with my fan for a while now (sudden and rapidly-switching on/off with no obvious relation to activity or temperatures (if I monitor the sensors)). So is there a connection? Better yet, a fix?

I’ve already tried upgrading the BIOS from its initial default to 3.17 and then 3.20 but both the fan issue and the ACPI Errors persist. I only just wondered if there was a possible connection on reading the above post, which I should probably have done before…

Does anybody have any ideas?

Thanks,  
D

For anyone else encountering these ACPI errors, they do not appear to be related to the fan issue I described. FW support described them as “more generic” and didn’t seem overly concerned. At any rate, a replacement fan fixed the ramping issue.
