Good questions, and beyond my ken. "idle=nomwait" did not prevent my system from rebooting while I was away. (I don't know if reboots and freezes are separate problems?) My BIOS doesn't expose anything like "typical current idle", and I have no way to upgrade it since the upgrade tools require Windows. Is there a guide out there for dummies like me to be able to collect kernel output from these reboots? (Does the kernel even get a chance to do/report anything? Would a report even be helpful to kernel hackers in figuring out more workarounds?) If I can contribute anything plausibly- constructive, I'd love to. Otherwise, I use and need this machine, so I'll probably just keep treating the symptoms by keeping it busy. (Which I suppose is another software workaround. ;^) -- 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
