Linux Mint completely freezes, rtkit-daemon related issues?

[minterRabbit]

I've been daily driving Linux Mint for the past 3 months on this new laptop and as of a the past 2 weeks it has begun randomly completely freezing - No mouse/keyboard input works, ctrl alt esc/F1 doesn't work, it seems the screen doesn't update either - I have to hard shutdown the laptop and turn it back to on.

I'm running Linux Mint 20.3 64-bit, Cinnamon 5.2.7, Linux Kernel 5.13.0-1026-oem, more specs below

It usually happens between 15 and 120 minutes into my session, there doesn't seem to be that much of a pattern to it. It seems whenever it does happen I have Firefox open, but I also tend to always be using it, so not sure if it causes anything or it's such a coincidence.

This is a beefy 32GB RAM laptop and sometimes the only only thing open is Firefox; I also have dual boot with Windows 10 on it and have tried using that for many hours with a combination of browsing/games/films and haven't had any problems, so I don't think it's a faulty hardware issue;


What I've tried from seeing other similar posts:
- Disable all window effects on Cinnamon
- Disable all non native applets and desklets
- Disable most Firefox plugins (I keep my password manager, adblocker and container tabs)
- Disable some custom startup applications programs I had
- Make sure there are no crontab related tasks running
- Update my system and packages

Lastly, I tried going through the journal logs, it seems the last thing just before freezing is often rtkit-daemon supervising multiple things in quick succession - Below more details:

Here's another log from a week ago https://pastebin.com/MKDSq6zK, you can again see the same rtkit-daemon messages - Anyone have a idea what could be wrong?

So after trying to find out which programs use rtkit-daemon with

Code: Select all

sudo apt-cache rdepends --installed rtkit

I saw only Pulseaudio comes up and going through the logs it also seems to be the only thing associated with it;

This post viewtopic.php?t=342236 suggest turning off the auto suspend function, I'm thinking this might be it since I left Mint with just a VLC video playing for a hour and there was no crash, hopefully this will work, will update soon.
