Likely not bad hardware. My 1700 was RMAd for the segfault issue (another pain point), and has passed all testing. Memory has been tested as well, many times over, with different profiles and settings. Tiny i9-9900 itx ready for transplant. I feel dirty. https://i.imgur.com/fTvWrWd.png -- 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

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

Asrock Fatal1ty X370 Gaming-ITX/ac Ryzen 1700 After the most recent Asrock BIOS update I haven't had any more crashing. I do not disable C6 anymore. This was a BIOS update to support the new Ryzen 3xxx chips as I was eyeing the 3900x and wanted the motherboard to support said chip if I had a weak moment and actually bought a 3900x. -- 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

The segfault compilation issue is well known. I had the same with my first 1700. AMD will RMA. My replacement chip has been fine. As for the other idle lockup issues, a combination of custom rcu kernel and python script to disable C6 has had my machine up for months. -- 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

Thanks. I'm in the same boat with C6. I know I'm a small fish but my company won't be using amd hardware until this is worked out. -- 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
