I have the Celeron version and upgraded the RAM to 4GB. I setup ubuntu with xbmc in dual boot mode. Everything plays fine but I am seeing high CPU usage. I did see this listed as a known issue however the first post mentions that this does not affect if RAM is upgraded to 4GB. However, I am still seeing this issue. I dont see any processes using the CPU so much in htop but the CPU percentage sometimes pegs a single core to close to 100%. Does anyone know what is consuming the cycles or if there is any fix for it?

The high CPU is related to single and dual channel RAM. So if you upgraded to 1 4GB RAM stick it could still cause the high CPU usage. 2 sticks of 2 GB RAM should solve the problem . (or 2 sticks of 4 GB RAM).
