(Why would Shuttle design an AMD motherboard with a integrated graphics which crashes the system if C&Q is turned on? Good question. Shame on Shuttle.) I initially reported that Windows worked fine, but although I did have AMD CPU driver installed on Windows, C&Q wasn't turned on in the "power options" control settings. Once I did that, Windows started crashing with the same symptoms as well until I turned it off again. I then turned off powernowd in Ubuntu and haven't seen it crash since. I'm guessing I never saw this in Gentoo because it did not have powernowd activated by default. At any rate, this is not a kernel issue, sorry for the trouble. Davor P.S. I am not on this list, so please email me directly with any comments or questions.
