I am still receiving lockups even with the latest BIOS, all the BIOS setting recommendations here, and with the idle=halt kernel parameter.
Although I am now fairly certain that I have a faulty motherboard (x470) which seems to be getting worse, and sometimes doesn't even get to the BIOS at all (I should have suspected something was up when I first bought it and the PS/2 port didn't work). I'm going to try replacing it and hopefully that'll help. -- 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
