Well I've got 7.2R booting on this motherboard so I guess it's safe to 
keep it.

After some trial and error the problem seems to be device sbp in the 
kernel config file. Comment that out and rebuild kernel and it boots.

Here's a backtrace from 7.2R using a GENERIC kernel (with sbp enabled) 
with debug options added.
