http://ubuntuforums.org – I've got the latest Ubuntu (11.10) installed on my little Acer Revo. All the h/w works great, including HDMI output to my receiver (and subsequently TV). The problem is that it hiccups when playing music via RhythmBox. Sometimes for a 1/2 second, sometimes for 3-4 seconds at a time. The frequency is random, once every few songs or so. (Hardware)
