Network semaphore error

[Richard M. Barry]

I'm getting a run-time error when I run RTEMS on a custom StrongArm 1100 board we developed in house.  More details about the problem:

I wrote a network device driver for the HDLC comms chip on the board, put it in the bsp and compiled the bsp.  To test it I wrote a simple application that just opens a socket to listen on.   It all compiled fine, but when I try to run the application, it exits on a fatal error, saying it can't release the network semaphore (detailed output below).   It doesn't seem to even get into my network driver's code (I put a printf at the beginning of EVERY function in the driver to make sure), so it crashes out while trying to initialise the network code I guess?  Any ideas on where to start looking for the problem?   The application Makefile defines MANAGERS=all, and the system.h for the application is also listed below.   

Console output when running application:
