I used Zenstates-Linux from Kai-Heng Feng's reference to https://bugzilla.kernel.org/show_bug.cgi?id=196683 and things have been much stabler, I don't think I have seen a freeze since then.
https://github.com/r4m0n/ZenStates-Linux I have been updating all the while and rebooting, so hard to tell if something else got picked up, but I suspect the C6 disable did the trick. At some point, I might try enabling it back again, maybe after the 18.04 release. At this point, not sure if you want to keep this bug open, whatever works for you guys. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1753346 Title: AMD Ryzen 7 1800X system (Dell Inspiron 5675) randomly freezes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1753346/+subscriptions -- ubuntu-bugs mailing list email@example.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
