It seems we’re seeing this combination of X570, Ryzen 3xxx and RTX 2xxx quite a bit. It’s pretty random, sometimes 1-2 weeks can pass without issues and other times it’s every couple days.
One thing to note: after the latest chromium update, I don’t get a full freeze anymore, just a very slow system. Are you using chromium too or another browser?
I tried disabling SMT like some suggested but with no effect. OldToby’s workaround is our hope right now :-)
I’m having an uptime of 5 days no with this workaround. Fingers crossed…
