@Eduardo. Yes I've found that option before. It is disabled by default (so the default is not to try the power saving). I even tried to enable hoping that the power saving system would be smart and avoid the lock up but it didn't work.
What I am trying right now is to set the option "Overclocking Enhancement" that is supposed to do "It enables SenseMi Skew (artificially reading lower temperatures in order to trick XFR to boost longer and higher), Performance Bias and tweaks VRM settings to improve overclockability". I am specially interested on the tweaked VRM settings. (https://rog.asus.com/forum/showthread.php?97680-Overclocking- Enhancement) Interesting enough, if I only set this to Enable (no overclock, just default setting + this option enabled) it seems to make things better. As I said, I have a code that consistently triggers a lockup if I run in a loop followed by one hour of inactivity. I have been running this test in one of my system with the "Overclocking Enhancement" set to Enable and it did not trigger the bug for the last 24hs. I have just changed the other machine to test this as well. I'll keep the test running today and the whole weekend on both machines and report back. If anyone else is having the problem with a Asus X399 motherboard it may be worth a try and, please, report back too. -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
