With OpenSuse 12.3 I observe the following: With the standard configuration suspend to disk does not work. After the splash screen appears, the progress bar stops very early, the power button and the shift lock button start blinking, and the system freezes so that the only thing left is to switch off the notebook. This behaviour seems to be independent from various settings in /etc/suspend.conf. When I enter SLEEP_MODULE=kernel in a file in /etc/pm/config.d/ hibernate works. After resuming 8 additional kworker processes appear (the notebooks has 8 CPU threads). This happens after each resume so that many kworker processes appear after some resumes. The same happens after suspend to ram. This makes both suspend to ram and disk not really usable any more. Reproducible: Always Steps to Reproduce: 1. suspend to ram or disk 2. resume 3. show process table ps axu | grep kworker root 5 0.0 0.0 0 0 ? S< Jun15 0:00 [kworker/0:0H] root 7 0.0 0.0 0 0 ?
