Want to share this in case it helps anyone else. I stumbled across this issue after putting together a new Ryzen 2200G HTPC with AsRock AB350 M-ITX mainboard a few weeks ago. Would encounter random freezes every couple of hours.
After updating UEFI to latest version, updating kernel to latest 4.19-rc8, and Mesa to 18.2.2, I was still having stability problems (freezing with error messages in dmesg output). Made the changes in BIOS to typical current IDLE etc. and still was having issues. But then realised I had not updated the amdgpu firmware, so grabbed the latest version from https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux- firmware.git and everything seems to have been stable since then *fingers crossed*. -- 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
