So if you got message with "typical current idle" option: [Firmware Bug]: ACPI MWAIT C-state 0x0 not supported by HW (0x0) it means probe of this C-state failed and it must be avoided by kernel. Is there any difference between C-state list in OS with and without this option? I have only laptop with very limited BIOS and can't check.
And there only C0-1-2. What about C6? What says zenstates.py about that? Frankly, I have not tried this script - do not want disable power-saving features for laptop. Also some overclocking may solve this problem (see comment 103). Turn on "performance bias" or similar option in BIOS for testing. -- 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
