Hi folks, I’m getting a weird issue where sometimes my OS will… break. KDE freezes up and I can’t use it, but my applications keep running - and I can even alt-tab between them. Usually, a couple of the other applications will freeze up too, but there’s little to predict which ones it might be.
I thought this might be a KDE issue, but then I tried accessing a different virtual terminal. What happens there is that I put my username in, and then it hangs, not prompting me for a password… and then starts redirecting messages from the system log out to that unauthenticated virtual terminal. Which seems, well, odd, to say the least…
Looking in journalctl this seems to be a bug with the Linux kernel - I’ve no experience whatsoever with kernel bugs, what should I do with this? Is this something I can fix by upgrading or downgrading kernel? I’m currently on Linux 5.11.1-1, which is the latest kernel available through Manjaro Kernel Manager. The logs are below from a couple of times this has happened.
