I disabled the CS8900 ethernet driver in my eCos code.  I then connect
to Redboot on the board using GDB and attempt to run it.  This shouldn't
cause a problem since RedBoot doesn't have anything to do with PCMCIA or
the WaveLAN card, right?

By lockup I mean it freezes and won't continue.  I step over the macro
using "next" and it won't do anything after that.
It's just a basic server test application.  It reads from the incoming
socket, and echos it back to the client.
