At this point, we have not yet identified the location of the driver where it gets hung. Just everything got frozen once the 128 MB mark was reached.
My problem was different one. I _never_ got my board frozen due USB activity.
By the way, where could I get hold of the patch from Rodolfos? I did a serach and followed the link provided by Rodolfos, but the link when NOWHERE. Did Rodolfos submitted his patches to be incorporated to the U-boot trunk? If he did, where could I get hold of his patches such that I could better understand it and try it out? Thank you in advance for your help.
Here my patches:
