Re: geforce 6600 random system lock
I've test it on 8776 and 2.6.18 with RenderAccel On/Off , AllowGLXWithComposite On/Off. But I forget about 'Option "Composite" "Enable"' :P . I will test this also, but probably this nothing change. And yes, I have most recent BIOS for my mainboard.
As I wrote before, there is massive number of unhandled IRQs for sure belonging to graphics card. But I no idea this is cause or effect of error.
