I used the rifw=alfie with a 1700x on an MSI X370 Gaming Plus BIOS 7A33v5H with no freezing for 1 week. Computer was rock solid on older BIOS (7A33v55) for a year+ until BIOS update to latest.
I'm using low power idle option with kernel 4.14.111 opensuse 15.0. PC had kernel: [Firmware Bug]: ACPI MWAIT C-state 0x0 not supported by HW (0x0) - After BIOS update and gone now after patch in Comment 580 with rifw=alfie boot option. -- 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
