Actually, there are several workarounds known to work listed in this thread. I've been running a stable x1800 using the rcu_nocbs=0-15 fixes noted above for almost a year now. > This thread is utterly embarrassing for AMD, truly embarrassing. It's a nuanced hard to troubleshoot bug in a processor + support chipsets with a known workaround which only seems to happen on Linux... not really sure how that is "embarrassing". It sucks, it's new silicon. Welcome to being an early adopter. Look at Intel's heart-bleed and all the other major security catastrophes they've had in recent history. Stuff happens. I do wish AMD would address it, but they're likely reluctant to bring it up until they have a reliable fix (if it even is a fix on their end) -- 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
