I had this same bug in June 2018 and in the beginning of July 2018. It seems to be solved for me by " Look in BIOS settings for "PSU Idle Control" and set it to "Typical Current Idle" "
The bug was appearing about a few days (2-7) in low usage mode. I was using openSUSE Leap 15.0 before this and no bug. Then I switched to Leap 15.1 and the bug appeared for the first time (it had a newer kernel). Then I had about 3 weeks before finding this fix. Now I have openSUSE Tumbleweed with kernel 4.18.8. It was OK since kernel 4.14 and now it keeps on updating the kernel as usual and everything is OK. Thank you for providing this fix! -- 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
