I was wondering how important it really is to use a realtime kernel? For which application or setup? I’m using Homegear with openHAB on the same board to control some blinds, interfacing with the HM-CFG-LAN. So far the setup work’s perfectly smooth. (After digging up the 1.6 Snapshot if the Homematic binding). I’m asking because I would like to avoid to recompile a Kernel. I would need one for Ubuntu14.04 with non-pae, not really experienced in Kernel building.
