:What is the problem?
The firewire chipset is either trying to access invalid physical
memory or shared ram on the firewire chipset is asserting a parity
error on the PCI bus (usually due to not being properly intitialized).
Our firewire driver has the fixes from FreeBSD in 2007 and I don't
see anything else that could be the cause, so you may have to compile
up a custom kernel without the firewire driver (or, if you can, try
disabling it in the BIOS instead).
