FWIW: I have an ASUS Prime 370-Pro, Ryzen 7 1800X, currently running Kernel v5.0.17.
With "Typical Current Idle", and no kernel tweaks, that has run without "freezing while idle" for about a year. Yesterday I upgraded the BIOS, which for some reason reset the "Power Supply Idle Control" to "Auto". That prompted me to run a small experiment to see if kernel or other upgrades have improved things. They have not: the machine "froze while idle" (fairly promptly). I have now restored "Typical Current Idle", in the hope of another untroubled year. I note, however, that my cpu (0x00800f11) is running with firmware 0x0800137, not the more recent 0x0800138 -- if I am reading the table in Comment 612, above, correctly. -- 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
