Hi, just setup brand new Ryzen 5 2600 on Asrock AB350 PRO4 with ECC RAM with Fedora 29 and the box froze after only 3 hours uptime, right after we went home for the night, so it was fairly idle (< 0.2% CPU 99% of the time).
Luckily I had read this thread before buying, so I wasn't too shocked. I wanted to say "me too" because some were wondering if the 2nd gen Ryzens were affected: they are. Also, we were able to get a stack trace / panic output that was on the frozen screen in a phone capture jpg. If anyone wants that, I can attach it. It looks similar to other ones I've seen for this bug elsewhere. No NMI errors logged on our box though. We did the "idle: typical" bios tweak and the idle=nomwait tweak and the system has been 100% stable for the 2 days since. Not sure if it's relevant, but the box also has a NVMe M.2 SSD, a rust drive, a high-quality Japanese-cap 620W PS (but states min 0.6A on +12V, but the drives and mobo are drawing at least that), and a very cheap PCIe video card for server use. -- 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
