Hello everyone. I've been following this topic for a long time. I have the same problem on my Rizen 1700. For a while, I was helped by switching "Power Supply Idle Control" to "Typical Current Idle". For a while, everything worked fine for me with the value "auto". But then I changed something in the settings of my BIOS and the lockup began to happen even with the value "Typical Current Idle".
Motherboard: GA-AB350N-Gaming WIFI (rev. 1.0) Linux Kernel Version: 5.9.12 Then I realized that the bug is due to a combination of some BIOS settings. So far, I have managed to achieve stable operation with the following settings: "Power Supply Idle Control" -> "Typical Current Idle" "Power" (Tab) -> "ErP" -> "Enabled" "Power" (Tab) -> "CEC 2019 Ready" -> "Disabled" The settings on the "Power" tab are very important! Especially "CEC 2019 Ready (Enabled)" setting, with which lockups are repeated. I will try to change different BIOS settings to achieve stable system operation when the "Power Supply Idle Control" is set to "auto". -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1690085 Title: Ryzen 1800X freeze - rcu_sched detected stalls on CPUs/tasks To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1690085/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
