Did you load msr kernel module before (modprobe msr)? Do you have the possibility to slightly overclock? Isn't there a Bios switch like "Typical Current Idle"? Is there a possibility to switch of C-states completely in the Bios (just for testing to be sure your hangs are the same reason as here)? -- 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
