To make things looks more strange... I have a non-explicable development with this issue. When it appeared to me I was in the middle of upgrading some components on my system. I replaced my AMD FX-8350 with one AMD Ryzen 5 3600X and my Gigabyte GA-970a-ds3p motherboard with one Gigabyte X570 UD (along with new RAM dimms from 16GB to 32GB). RX580 stayed the same and also OS is the same (disks moved to the new motherboard, no re-install). Guess what... running with 5.7.7 for 48 hours now without issues.... problem has disappeared. I suspect a very rare combination of things maybe even not in the amdgpu driver itself... With 5.7.7 on my "old" configuration, I had the crash almost immediately after login like in the above comment.
Just to report that got the issue after some days with my new hardware setup, so it is still there, hope you guys pinpoint it soon!
