I am using ZenBook ASUS and after trying to install virtual box from ubuntu software center on ubuntu 11.10 unity, I faced with kernel panic and from that time from time to time I am facing with the same error! I used Wubi and have dual boot with Windows Home Premium with Ubuntu 11.10! I could also involve screen shots in case necessary!
PS: I did reinstall Ubuntu once again and now this time it happened while downloading a codec:

I should say I am installing ubuntu via Wubi! Any solution?
