What I found is that the reason the debugger wasn't hitting the break points
is that in quicc_smc1.c on line 318 when the communications processor module
was being reset, the code wouldn't return from this call.  I can't figure
out why this would happen only occasionally?

Any thoughts on this?

Sometimes there can be multiple cyg_user_start's floating around, and GDB
chooses the wrong one (it's a known problem), so be sure to set a
breakpoint on the cyg_user_start that actually gets executed.

Also try it on unoptimized code. Debugging optimized code can sometimes
(although fortunately rarely) fail.
