Since the fault address is 0x0 it's a NULL pointer dereference of some sort. A stack trace would be very useful if you can get one Tom. As a workaround, you can try unsetting the hints related to fd0 (i.e. variables in the loader that start with 'hint.fd.0') and see if that fixes the issue for now. If it does, then get the machine installed, build a kernel with debug symbols and KDB and DDB and we can look at fixing the actual panic. -- John Baldwin
