Subject: ifconfig: page allocation failure. order:2, mode:0x20 while enabling Jumbo frame

Hi
 On my Nas device (Linux kernel 2.6.22.7)  when I try enable to jumbo
frame the following error is coming. I  did not find enough information
from the net. So I  am mailing this. Please guide me  what is happening
here and How to resolve this error?
