Probably fucked up installation was the cause of this. sorry for bothering.
I recently reinstalled Kubuntu because I was frustrated with the stability of my system. It still hadn't really improved since switch to kernel 5.4 And, magically, all the crashes are gone. So, no idea why but something in my old system seems to have caused most of the crashes. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1852001 Title: KDE GUI freeze on high disk IO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1852001/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
