Comment # 18 on bug 917221 from John Leys

After removing the pm-utils package, i have been using hibernate/thaw with no
problems for 2 weeks.  I am not certain what problem is caused by pm-utils, but
removing it appears to be a solution.  I feel that this bug should remain open,
however, until the cause of the conflict has been identified, and/or an upgrade
path from earlier versions includes a migration of scripts that have been
modified by the user from /usr/lib/pm-utils/sleep.d to
/usr/lib/systemd/system-sleep/, or some other more user oriented directory that
contains scripts to execute on hiblernate/thaw.
