v3.16 kernel[0].

tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.

  ACER Aspire 5100 laptop Suspend/Resume Failure

Status in “linux” package in Ubuntu:

Bug description:
  On this old laptop, Ubunutu 14.04 works fine on boot (after making
  sure fgrlx drivers are removed).

  However after a Suspend/Resume the screen flickers/tears so badly as to make the system unusable.
  Note that the problem does not occur with Hibernate/Resume. In fact if I can get the focus into a terminal while the
  screen is flickering and do a $ sudo pm_hibernate, the screen will be okay on Resume.

  Separately the wifi (b43) vanishes after a Resume, but I'll file a
  separate report on that later.
