The bugzilla entry says "When reboot=EF=BC=8C the capslock key of thinkpad x1 starts blinking" which sounds like there's an oops that just isn't showing, quite possibly because the console has already been shut down. I didn't test this out, and would sincerely hope that somebody else is willing to follow up on it since I'm in the busiest part of the merge window.
