Title:
  Ubuntu 14.04 Beta 2 stuck at "Switched to clocksource tsc" when
  booting up, then resumes booting to the login screen, after 1 minute

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  On Ubuntu 14.04 Beta 2 (Final Beta), it takes remarkebly long to boot up into Ubuntu.  Ubuntu gets stuck at "Switched to clocksource tsc" for a almost 1 minute or longer, then it resumes booting up to the login screen.  On Ubuntu 13.10 it only takes about 7 seconds to get to the login screen, while it takes almost more than a minute to get on the login screen on Ubuntu 14.04 Beta 2. I hope this issue could be fixed.
   
  I have the Acer C720 (chromebook) that has been enabled to use legacy boot so I can use other OS's.  Other Acer C720 users have been faceing the same problem also.
