Weird graphical trash/hard lock. 6600 AGP
So I've been having this problem for a bit... seemingly randomly, whether in a 3D game or a 2D desktop (though more quickly in the 3D) the screen will get trashed with some kinda weird repeating pattern that covers the whole screen. Shortly thereafter it takes Linux down with it. I say randomly because it takes anywhere between 10 minutes and 8 hours, in both environments.
It's happened with SBA, AGP 8x and Fast Writes, as well as nothing by AGP 4x. (Maximal and Minimal).
It's happened in 7676, and the 8 series too. I'm running 2.6.14-r4 x86-64 on an AMD64 3000+, Gentoo. I'm thinking maybe it's a heat or power issue, as my system runs pretty hot (I underclock my proc. to 1.8GHz).
What do you all think?
Can I under(clock/volt) my 6600 AGP in Linux?
