Hi Aurelien,

Ahhh I see now - there was a change a while back to the way in which 
boot ordering information was passed from QEMU to OpenBIOS (with respect 
to default devices) in order to determine default boot devices. The net 
result was that things didn't work without an explicit boot device 
specified added to the QEMU command line.

At the moment, you should be able to boot by adding "-boot c" to your 
QEMU command line. I'm not sure why that particular commit triggers the 
bug in your case though. Do you think that booting QEMU in this way 
without a specified boot device is a bug? If so, any insight as to what 
causes this would be gratefully appreciated.


ATB,

Mark.
