[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
Dear all,
Would it be 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

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.
