If it is a SDRAM (DDR/DDR2) configuration issue, it likely is the DMA 
happening from network activity that is aggravating your 
misconfiguration.  See especially the state machine part of
   <http://www.denx.de/wiki/view/DULG/SDRAM>

Using DMA makes addresses and sequences and timings jump around that 
simple program execution (especially if you have cache(s) disabled) 
doesn't do.
