As Andreas reported that his stability got better when he disabled firewire in his BIOS, maybe you could either do the same or remove the firewire driver? What is absolutely possible is that a bug in a driver does not cause direct crashes, but instead results in memory corruption (some memory freed by the driver and then overwritten again while it was in use by something else). This could then result in the random and inconsistent crashes you get. Regards Michael
