In light of the last few comments here I can say that I may have been confusing 2 separate issues: The random segfaults and the lockups. I tested idle=halt a while back and I may have inadvertently concluded that it didn't work due to my machine still receiving segfaults, which I was assuming would eventually lead to a lockup. Likewise, the solution I mentioned earlier (disabling PAGE_TABLE_ISOLATION) seems to have fixed my crashes, but my machine just locked up. I've set idle=halt again and this time I'll try to keep the two issues separate and only post back here if I still receive lockups. Thanks for clarifying the issue. -- 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
