I am sorry if I was not clear before, those messages are always present even on a "good" build. The issue is that on a "bad" build they hold back the boot process from continuing. USB functionality is never affected. > As that xhci commit you point at is showing an issue, are you sure that > you are properly building the right xhci driver into the system?
