I suspect the faster CPU means changing your memory controller timings, 
and something's not right there.

Alternatively, the faster code execution may have resulted in some other 
thread in your system trying to do lwIP things before lwIP is fully 
initialised, which maybe (theoretically - it just depends) might cause 
problems.
