Hi ! I haven’t read all the comments here because there are too many by now, but I’m puzzled that many consider this to be a Linux-only issue, because I can tell you that it definitely happens on Windows (10) too, and I found other people with the same freeze/reboot problem on Windows. For me the crashes are really the same on both Linux and Windows. I have a Ryzen 7 1700X and an Asrock X370 Taichi mainboard, and the "Power Supply Idle Control" > "Typical Current Idle" setting fixes the problem. However, lately I’ve noticed a couple of times, but still rarely, that the computer would crash and reboot when waking up from sleep, then it seems to enter a boot loop for a few times, and then starts normally but it resets the BIOS settings… I haven’t overclocked anything. My CPU also seems to have the "Ryzen segfault bug", which seems to be a different issue from what I’ve understood.
I should probably RMA the CPU (and the mainboard ?), but I haven’t because disassembling everything would be difficult for me. In my case those crashes (without "Typical Current Idle") happen fairly rarely, like every two-three weeks, or even more rarely than that. -- 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
