so you finally gave up like me and most others i will also look into ubuntu 11.04 later when it is improved, but for now im sticking to 10.10, it just works. But will say i have not had any unstable issues in 11.04, just big ignorance again and again. My minecraft server still runs 11.04 and it has and uptime of 7 days now, but before that it was running fine with an uptime over 23 days. So i can not claim unstable from there, but it only runs minecraft server, nothing else, so i can't say for sure if it where to crap out on me with "normal" usage.
