[Bug 1390780] Re: [Samsung NP-N220-JA01FR] Intermittently does not resume from suspend


Christophe, the next step is to fully reverse commit bisect from kernel
3.2 to 3.18 in order to identify the last bad commit, followed
immediately by the first good one. Once this commit has been identified,
then it may be reviewed as a candidate for backporting into your
release. Could you please do this following
?  Please note, finding adjacent kernel versions is not fully commit

Thank you for your understanding.

  [Samsung NP-N220-JA01FR] Intermittently does not resume from suspend

Status in “linux” package in Ubuntu:

Bug description:
  Sometimes (randomly, but more often after a long while of being
  suspended), my laptop cannot wake up from the suspended to ram state.
  It is a samsung n220 netbook, with ubuntu 12.04 precise and 3.2
  kernel. When the system hangs on wake, and I try to hit the caps lock
  key, the led does not light up, meaning (I think) that it's not a
  problem of video card, but a real kernel hang. It happens 1 over 5
  times when I make my suspend my system to ram.

  WORKAROUND: intel_idle.max_state=0 or 3 kernel parameter, but the
  battery discharge rate shown by ubuntu is increased by at least ~1W.

  AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
