I tried and it didn't help. After freezes started happening at Xubuntu 18.04LTS with stock 4.15, I compiled latest 4.20.3 kernel and added CONFIG_RCU_NOCB_CPU=y, as it was suggested here, but freezes didn't stop. There's my dmesg at comment 492 with latest kernel. -- 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
