Actually, any code.  The twothreads.c example will cause it to happen.

What happens is that once I hit a breakpoint I cannot seem to continue.  If I 
disable all the breakpoints (including the ones on 'main' and 'exit' that are 
normally set when you select your target) the code runs to completion.  If I 
hit the stop button, the target is reported to not be responding.

I have discovered that I CAN set breakpoints before cyg_pci_init() but I 
haven't found exactly where it breaks.  It may be thet cyg_pci_init() is 
killing it or the setup of my ethernet driver, or something farther down the 
line.  I'm still tracing it to find out exactly which function causes it to 
die.  I am pretty sure it's a function cyg_pci_init() calls, but I'm still in 
the middle of working on it.

Also, I am working with Insight under Linux.

P.S. I am using the following ecosconfig lines to setup my kernel:

 ecosconfig new iq80310
 ecosconfig add net
 ecosconfig add CYGPKG_NET_ETH_DRIVERS
 ecosconfig tree
 make
