@Daniel what makes you think this bug is fixed? It certainly isn't for me. I have a ASRock Fatal1ty X370 Gaming X motherboard, a Ryzen 7 1700 CPU, have updated the motherboard BIOS to its latest version (4.80 with PinnaclePI-AM4_1.0.0.2 Patch A) and am still getting idle lockups with kernel 4.15.0-32-generic (Ubuntu 18.04.1 kernel). The workaround for me is to disable C6 states using the Zenstates.py script (which has the unfortunate side effect of lowering the max CPU frequency in single- threaded mode).
(I also don't see any "Typical Current Idle" option in my Setup options, though I might have overlooked it) -- 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
