Looks like they've addressed Ryzen errata issues around August 2018: https://github.com/freebsd/freebsd/blob/75ee4f08d3acd4bf70f24b3203fa440255873973/sys/amd64/amd64/initcpu.c#L133 Also, they've made machdep.idle=hlt and machdep.idle_mwait=0 default for Ryzen processors. I've additionally checked the registers mentioned in FresBSD's source. Latest BIOS 4406 (w/ AGESA 0070) for my ASUS A320M-K seems to apply fixes for all affected errata. Eventhough I can't reliably reproduce the stability issues anymore, I think it's still good practice to have Boris' patch applied, since it's addresses a known erratum. I'll test the patch and check for regressions. -- 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
