Don't know. So you are booting the same kernel over network as on the 
disk, and it works for you when you netboot?

I can definitely show that for me, booting from disk, if I use one 
amount of disk, it does not detect mscpbus1, but if I just configure the 
system with less memory, it do detect mscpbus1. Same kernel, same 
everything else. Literally, the only thing I change is the memory size.
