The bug doesn't seem to appear anymore with the latest 3.18 kernel. Only
doesn't seem. But I have to revert to the old kernel as my screen
backlight cannot be dimmed anymore.

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

Status in “linux” package in Ubuntu:
  Confirmed

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's hard to know when the problem appear. It happens 1 over 5 times when I make my suspend my system to ram.
  Following various hints on the launchpad pages, I tried to put the intel_idle.max_state=0 or 3 to the kernel parameter. It seems to work but then the battery runs out of energy more quickly (and the battery discharge rate shown by ubuntu is increased by almost 1W at least).
  How could I track what causes my system to not wake up properly ?
  Thank you.
