Staudey I also have those from time to time, though very rarely in the last few months. What's you hardware?
Used to have them bad. Then less bad. Then every other day. Now very infrequent, but they happen.
But now........
I HAVE NO FREEZES EVER when I login and walk away. Shower. Drink some water. Then open a file. Then in a few minutes my password manager. Then eventually the browser. Give Solus 20 minutes to wake up before taxing it.
I HAVE FREEZES EVERY TIME I login, immediately launch some apps, documents, my password manager, and my browser, then, boom, FROZEN.
I know there may be other factors, but it's my correlation, and the way I've been doing things mostly freeze-free for at least 7-8 current kernels ago.
