I have a Ryzen 5 3600x and I have the same issue. I get freezes where I can't move the cursor and the only fix is manually rebooting the PC. Data corruption is something that I'm already experiencing here. Not sure what to do. I'm not using Ubuntu, though. It is also reproducible on Ubuntu, although less frequent. I could reproduce on Ubuntu Desktop 20.04 Live DVD after more than an hour of watching videos and all that.
I've created a bug on kernel bug tracker because it mostly seems like a kernel bug: https://bugzilla.kernel.org/show_bug.cgi?id=208615#c1 ** Bug watch added: Linux Kernel Bug Tracker #208615 https://bugzilla.kernel.org/show_bug.cgi?id=208615 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1865293 Title: ryzen 5 3600x soft lockups To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1865293/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
