Intel AX20x bluetooth disconnecting intermittently since linux-firmware 20210208 update
Since an update around January/February, me and several others have had issues where our bluetooth headset would disconnect after a while (a few minutes up to a few hours) and then reconnect 10 seconds later. See this thread on the Archlinux forum where the issue is discussed: https://bbs.archlinux.org/viewtopic.php?id=263806
It looks like the issue is caused by the

We first thought it was fixed when downgrading to pulseaudio 14.0. However, this seems to have only delayed the disconnection issue by an hour: instead of disconnecting every 10 minutes it only disconnects once every hour or so.
The issue is hard to test because the disconnections seem to be rather random. I got a hunch that it happens more often when audio is being played as opposed to just having the headset connected 'in silence'.
Steps to reproduce
This issue is hard to reproduce because the disconnections happen rather randomly. Install pulseaudio 14.1 or later and connect a bluetooth headset. After listening to audio for some time, the bluetooth headset will disconnect.
What is the current bug behavior?
The device disconnects and reconnects.
What is the expected correct behavior?
The device does not disconnect.
