(In reply to linuxannoyance from comment #618) After I posted this comment, I have not had any more random crashes. I disabled Global C-States in my motherboard's firmware, as that was the only option relating to C-states (C-6 states not being available). Based on my experience and other comments in this issue, I believe disabling Global C-States is what has caused my system to stabilize. I recommend this as a viable option for people with older motherboard firmware who don't want to flash it.
I still think this is an embarrassment for AMD. I do not know how they intend to take the server market when they allow an issue like this to persist. Maybe Epyc gets better support. Even so, I am a desktop and laptop Linux user, and I will mention this issue to everyone I meet who is looking for personal hardware to run Linux on. -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
