Problem description
I bought raspberry pi 2 a week ago to replace an old raspberry pi model b (with xbian too). Since yesterday, Kodi always freezes after a minute or so. I didn't install nothing since second day. I tried to disable cec and change post-start script timeout without results. After screen freezes, the remote control respond with sounds for a while when I touch it. And then kodi shutdown.

In the log file I think that this event occur on line 1034 or so. Before that I think that the log is normal.

Any solutions or clues about this??

Sorry for my bad english.
