Well, according to my journalctl log, it seems to always be triggered after=
 a
power state switching. It doesn't do it from boot (power state 0) to
performance (power state 1), but it is later. Strangely, I see a=20

...
Sep 25 20:28:28 Xander kernel: switching to power state:
Sep 25 20:28:28 Xander kernel:         ui class: performance

Why would it try to switch from power state 1 to power state 1 (the same po=
wer
state)? And why is it at that moment the problem arises? I'll have to do mo=
re
tests to see if this behaviour happens each time.
