I applied the latest asrock BIOS with new options "amd cbs global c-state control" to disable voltage lowering when idle.
Even with all BIOS settings, custom kernels and params, disabling C states, power supplies and so forth I'm done. 2 years of this BS. I picked up a 65 watt Intel i9 9900. Good luck to you all and thanks for all the ideas and help. I hope to revisit AMD Ryzen based linux servers in a few years. -- 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
