I have attached /var/log/kern.log. This file shows, e.g., that I
*successfully* suspended my computer on July 3, 00:30 and resumed it on
July 3, 07:13 but that I *unsuccessfully * suspended my computer on July
3, 20:08 and rebooted it on July  3, 22:13.

Title:
  HP Elitebook 8560w sometimes freezes when it should suspend to RAM

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Sometimes when I want to suspend my HP Elitebook 8560w to RAM by
  pressing "fn + f3" or by clicking on "Sleep" in the KDE menu, the
  computer starts the suspension process but it does not turn off.
  Instead, a black screen with white letters is shown (I removed the
  numbers in square brackets before each line):

  PM: Syncing filesystems ... done.
  PM: Preparing system for mem sleep
  Freezing user space processes ... (elapsed 0.001 seconds) done.
  Freezing remaining freezable tasks ... (elapsed 0.001 seconds) done.
  PM: Entering mem sleep
  Suspending console(s) (use no_console_suspend to debug)
  _

  The only thing on that the computer reacts is to press the power
  button for 3-5 seconds which turns the computer (completely) off so
  that it cannot resume but has to reboot. I have this computer since
  November 2011 and I had always the latest Kubuntu version installed.
  The bug never happened until and including Kubuntu 13.10. However, it
  occurs on average at every 5th to 10th suspend to RAM since I upgraded
  to Kubuntu 14.04. I have updated the BIOS to the latest version but
  this did not change anything.

  It seems that I can only attach one file at a time. I will attach files with further information in a moment.
