Interestingly, I had a nicely running system, uptime about 30 days, and I just decided to upgrade the Kernel to the latest (Fedora 28), and "what the heck" I will just upgrade the motherboard BIOS too.
Mobo: ASUSTeK model: PRIME B350M-A 6 core AMD Ryzen 5 1600X Six-Core (-MT-MCP-) arch: Zen rev.1 So, now I have BIOS version 4104 (previous was 3801 I think) And after like 10 minutes of doing stuff (i.e. not idle), LOCKED UP !!! So I went into the BIOS and changed the Global C-State to Disabled, and right under that is the power profile, changed it to Typical. We shall see how long it lasts ! I guess "don't fix what ain't broken" applied to my activity today lol. -- 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
