When I have seen a soft reset at this point it has been due to a memory 
problem. Try simpler configurations and try putting some basic memory 
test just before CAR is disabled. I would try on the interesting 
boundaries. For example, check where LinuxBIOS gets copied at 2MB and 
across a dimm boundary like 1GB+2MB.

	ram_check(0x00200000, 0x00200000 + (640 * 1024));
	ram_check(0x40200000, 0x40200000 + (640 * 1024));

Also, most of the memory registers are located in Function 2 if you 
decide to dump and compare them.
