Issue with Ubuntu 10.10 on beaglexm board

Hi,

I could successfully create a woking sd card of my ubuntu10.10 for
beagle board xm...

Then I intalled all the necessary packages into that and archived the
sd card to a tar.bz2 file for further usage.
I did all these from my ubuntu 10.10 PC...

But, now, when I am trying to create a new sd card from the tar.bz2
file from a 10.04 Linux PC it is not working.,..
(Still the same untar-copy is working fine in a 10.10 machine)

The corrupted sd card when boots up, shows the following erro
messages.
