Hi, another Michael here. The typical idle current fixed the trouble, if you have still freeze under low load after it's: a bug in the uefi that doesn't really apply the "typical idle current"(disabling partially core parking). another problem than the one on this thread.
I want to add another thing, about fixing it directly from the kernel. As typical idle current seems (i am testing it again for see) not needed under the other OS, that's because the core parking under this other OS is partially disabled by DEFAULT on this OS as i said earlier in this thread. So it seems possible to fix it via the kernel, without make use of an uefi parameters not enabled by default. It could increase the user experience under Linux for people who doesn't know this trouble. So, why don't make simply the same on Linux? IIRC from my reading over hardware.fr article the same apply to Intel cpu. That's a tweak for increasing performance afaik. Ryzen gains ~10%(on games, where latencies are more important) while not having "deep sleep" of cores enabled. My Wattmeter is not a good one but i see mostly no difference between this core parking partially disabled or not. It must save really few power. You all can easily test it by core parking control software on this other OS. -- 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
