AGESA 0070 has been released for some mainboards (e.g. ASUS A320M-K, ASUS X470 Pro and a couple of MSI boards). For anyone experiencing crashes, I think 0070 is worth a try. Official changelog says something along "added support for new processors", but more changes under the hood aren't unlikely.
Regarding the segfault issue: it has already been confirmed by AMD to be a hardware issue on early batches of Ryzen 1xxx CPUs and you can RMA affected CPUs under warranty. I don't have the landing page at hand right now, but I'd advise anyone with the segfault bug to replace their CPUs; especially those experiencing crashes under Windows. Like Trevor, I also think we have incostencies, because we're most likely dealing with multiple bugs. From what I've seen so far, Vega users have a different form of crash caused by Vega (including Ryzen Mobile, Vega 56/64 dGPU, 2200G/2400G), users experiencing crashes under Windows and Linux have a different form of instability issue, crashes caused by segfault is another category and issues fixed by idle=halt / "Typical Load Idle" is another category. >From my own tests, I fall into the category fixed by "Typical Load Idle". Later today, I will update to AGESA 0070, test against latest kernel with various settings and report back. -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
