            Bug ID: 339391
           Summary: system hangs during suspend-to-ram (must poweroff),
                    while pm-suspend works.
           Product: Powerdevil
           Version: unspecified
          Platform: Kubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: plasma-devel at kde.org
          Reporter: figjina at libero.it

System: dell-xps13-sputnik-2014 (Intel i7-4650U), 8GB ram, NO SWAP SPACE (maybe
relavant?)
OS: Kubuntu 14.04  x86_64 with kernel 3.16.0-17

In systemsettings->power-management I set suspend-to-ram on lid-close event.
Then when closing the lid, the laptop seems to suspend (blanks screen) but cpu
stays on and system freezes with no possibility to restore (also sshd does not
respond). The only option is forcing shutdown by holding power button.

Besides, a simple 'sudo pm-suspend' in the terminal works just fine.

Reproducible: Always

Steps to Reproduce:
1. set suspend-to-ram on lid-close in systemsettings->power-management
2. close the  lid

Actual Results:  
partial suspend and system hang

Expected Results:  
the same as using pm-suspend
