Fans are spinning for no good reason after suspend
Open, HighPublic

Description

When resuming from suspend, my fans are often spinning even though the computer isn't doing anything that would warrant it (and they don't stop even when closing all applications or even rebooting). The only thing that fixes this is powering down the machine.

In this state the computer is also generally slow and unresponsive (even when not a single app is running).

This does not happen every time the machine wakes up from suspend, but often enough that I think there's a causal link (about 2 out of 3 times).

Is there anything I can do to help find the cause (collect logs, etc.)?

My machine is a 3rd generation Librem 13, running stock PureOS with GNOME Shell.

It would be great to get some more information on the state of the laptop when it is hibernating. I'm setting up something called "tellerstats" with lm-sensors (which are both in PureOS) to gather more info so I can see if I can reproduce the problem.

I received an update from the coreboot team regarding this problem. It apparently is not a PureOS issue only, it affects other OSes too. The quick fix is to suspend and resume again (obviously not a permanent fix). The coreboot team suspects it could be related to some ACPI setting in coreboot, but they haven't been able to find anything conclusive.

I can confirm that the suspend/resume fix works
