Title:
  Black screen on resume after suspend

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I have an Acer V5-573G which fails to resume from suspend for all
  kernels past 3.14.51 (I've tested 4.2.0-040200 and it still doesn't
  resume). When attempting to resume, the hard drive spins up, the
  keyboard backlight turns on, the suspend light goes from orange to
  blue, but the screen stays resolutely black and the only keypress it
  seems to recognise is alt-sysrq-b.

  I think this is a duplicate of
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1416557 (where
  I've left more information) and
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1429347 and
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1389202.

  I suspect that the resume problem has something to do with the changes
  made in https://01.org/suspendresume/blogs/tebrandt/2013/hard-disk-
  resume-optimization-simpler-approach. These were made between 3.14.51
  and 3.15.0-RC1, I think.
