Ard, could you take a look? I managed to hack multi ram bank support into kvmtool, so I can now repro the issue in virtualization. Then was able to bisect to get to the above commit. I'll keep digging to see if I can get to the root cause, but I suspect Ard is best placed to hypothesise at this point. Thanks, Ryan
