But so is mine. It is perfectly reasonable to expect my method to work just as well -- the 7->8 is not revolutionary, but simply the next step.

The link above describes a crash in the BIOS (and no POST), if firewire circuitry is disabled in BIOS. My problem is with FreeBSD kernel hanging on boot, if the firewire circuitry is enabled in BIOS. The boot was fine under 7.x, so this can not be due to a BIOS-bug -- the only thing, that changed, is the OS... > This is also a commonly-reported problem (and one I've harped on as > well).
