I don't have time for a proper reply, but here is some reading for you: http://ivtvdriver.org/pipermail/ivtv-users/2009-August/009528.html http://ivtvdriver.org/pipermail/ivtv-users/2009-August/009532.html http://ivtvdriver.org/pipermail/ivtv-users/2009-August/009539.html It's all very disheartening. You essentially have to experiment your way through an enormous amount of unkonws to figure out why the PCI chipset on your motherboard is unhappy enough to reboot the system. All with no error logging about the triggering event. The labor cost alone is probably more than the price of another Desktp PC with a new video card. In the end, Jeroen did actaully find the problem on his system. It was caused by a change in the kernel that modified the way his motherboard PCI chipset was set up.
