Andriy, I think this is related to an issue I was experiencing two days ago. I tried to boot an 8.0-CURRENT system off an USB thumb drive and it worked fine on some machines, but failed with mounting root (off the thumb drive) on some others. I think we need some more delay to give drivers the chance to complete device probing before the root mount is being tried but I hate to just blindly hack a delay somewhere. Will check that issue, eventually next week.
