I just did the 10th fresh install but the problem remains. After some minutes kodi freezes and nothing happens anymore on the screen but the raspberry is still reachable over ssh and even the web interface is still available though nothing happens if I use the remote there either.
Well @mcobit you are most likely correct. Just may have looked to fast

Linux osmc 4.4.0-1-osmc #1 PREEMPT Tue Jan 12 21:00:44 UTC 2016 armv6l GNU/Linux
Actually it is a Pi1
Jan 01 01:00:19 osmc kernel: Machine model: Raspberry Pi Model B Rev 2
Besides some more fresh installs I tried the following so far - but still it stops working after a while:
-install osmc over noobs
-take a different sd-card (actually tried 2 different ones)
-replace the network connection (ok this happened only because my wifi dongle finally arrived)
-Use a different power supply. I just had my sony phone charger which is supposed to have 2000mA. But it did not change anything. Just bought a “special” 2000mA raspberry pi charger
The only thing that changed so far is that now, when it freezes, I do not even have a working ssh connection anymore. But this is only the case if I use noobs.
