[Bug 1509723] Re: [Acer Aspire ES1-311] Ubuntu freezes occasionally



It should work. I hope it will but unfortunately this is not the best
solution. These Intel CPUs use very advanced power saving technologies
and C-state is something that is in connection with power saving. The
more bigger c-state number is in use the more energy efficient your cpu
is. "C-state 1" is a very strong limitation, it was introduced by

  [Acer Aspire ES1-311] Ubuntu freezes occasionally

Status in linux package in Ubuntu:

Bug description:
  I am running Ubuntu 15.10 and my notebook freezes occasionally. I had
  the same issue with Ubuntu 15.04, but I thought that 15.10 might
  change it. I am running Ubuntu on an Acer Aspire ES1-311 (P1D5).

  I have no clue what causes this, my system just freezes and I can't do
  anything anymore. ctrl+alt+f1 doesn't work as well as alt+print+REISUB
  doesn't work either. It's just frozen. I have to power down manually.

  Last time I was programming only with a gnome-terminal and atom
  (editor) opened. I checked some log files but I couldn't find anything

  Any ideas?
