Hi Andrew,

> I have been sent an Efika[1] board from Genesi.

  Good one !

> Has any one got any suggestions how I could fix this?

  The physical pages for the message buffer are stolen from what the 
system thinks the actual physical pagemap is. You may want to check this 
and see if it's OK: it is obtained from OpenFirmware in the mem_regions 
function:

Peter.
