Marfitalu: thats the same message which i get when i shutdown my laptop .. i dont get it all the time .. but sometimes i do .. its quite annoying .. and a irritating blue color :)
Marfitalu: That normally means that you have a problematic driver installed. My WLAN Module caused that over months ;) Maybe you can remove it by updating all of your drivers? (I bought myself a new WLAN card , since mine was from a cheap manufacturer with crappy drivers )
