[Bug 1308264] Re: Ubuntu 14.04 Beta 2 stuck at "Switched to clocksource tsc" when booting up, then resumes booting to the login screen, after 1 minute

 

*EDIT*


im new to fourms... so please excuse my errors... i just had a ubuntu one acount so i signed in just to tell
Hans Zaaijer (h-l-zaaijer) in case you didnt figure it out yet...(i know im 4 months late...)(i love periods)

""Hello all,

Is it possible to describe step #1 in Suthars solution (= "downgrading the kernel") in more detail,
(step by step) for this beginner?
How do I download and install 3 new kernel files exactly?
(Steps 2 etc I can understand, only step #1 is too abstract).

Thanks in advance, I really want to use Ubuntu on my Acer C720,
but the boot (1 minute) indeed is too slow.

Regards and thanks from Hans""

OPEN TERMINAL and use those commands 
Also the "$" must be removed to be used in ubuntu

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.
