zzz won't really work until we have proper graphics (drm) support for these CPUs. I'm working on that, but it is a significant amount of work. The ZZZ problems could be related as well. I expect there to be "issues" if you're running X for example. You say: > - Most failures are not recognizing hibernation (`/ was not properly > unmounted') Is that because the machine crashes during hibernation, resets during unhibernation, or does it simply not attempt to unhibernate?
