Urm..I&#39;m always suspending to RAM and getting back my JACK session with just 1 XRUN increment, that&#39;s all. I just reset it. I&#39;m using KLaptop to do that. I assume you do mean suspend to RAM when you say &quot;hibernate-ram&quot;. Or are you talking about hybrid (save image to disk, copy image to disk and suspend, upon failure image exists on disk)?<br>
