Ah got it - it's a bug in the OFMEM freelist code whereby it doesn't 
honour the physical alignment if the space is reallocated from the 
freelist. The attached patch seems to fix the problem for me - can you 
confirm at your end?

Would you like me to re-spin the entire patchset based on previous 
comments to the list for more testing, or do you think it's close to commit?


ATB,

Mark.
