This is still an on going problem. It was working fine on Mint 18.3, then I upgraded(downgraded?) to Mint 20.3 I have been having lockups, freezes, ssh in for a while before it locks up, etc.. Very similar to above mentions of problems.
Here is the basic error that happens: [37664.592883] radeon 0000:01:00.0: ring 0 stalled for more than 14948msec [37664.592889] radeon 0000:01:00.0: GPU lockup (current fence id 0x00000000003b1a11 last fence id 0x00000000003b1a26 on ring 0) Here is the system info: System: Kernel: 5.4.0-109-generic x86_64 bits: 64 compiler: gcc v: 9.4.0 Desktop: Cinnamon 5.2.7 wm: muffin dm: LightDM 1.30.0 Distro: Linux Mint 20.3 Una base: Ubuntu 20.04 focal -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1707695 Title: radeon 0000:03:00.0: ring 0 stalled for more than 10000msec To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1707695/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
