I've been having this issue with Fedora 28 and I can't figure out the issue. Maybe a more experienced linux user could help me out. My Desktop Environment is gnome.
Every so often my computer will completely freeze. And the last 3/4 of a second of audio will loop. I have to hard reset the computer when this happens. I've reinstalled Fedora 28 and it still happens on the new installation.
I'll probably need to provide more information to diagnose this issue. It does it on LightDM and GDM (if that means anything) but I haven't tried another desktop enviornment. I've tried different versions of LLVM and MESA (I use AMDGPU)
I don't know what other infos are needed to see what the problem is. probably something with journalctl?
