By break do you mean breakpoint?  (there should be a red bullet in the
fringe by breakpoints).  If so, how does the breakpoint get set?  I'm not
sure what you are saying here.  Sometimes if the source is already in another
window and execution goes there GUD will display in that window and not the
dedicated source buffer.

To generate a log of the transactions between kgdb and Emacs can you please
do the following:

1) Set gdb-enable-debug to t using M-x set-variable.
2) Do M-x gdb and start kgdb with the arguments you are using (and tell me
   what they are).
3) Type 'n' or 's' to get the source buffer to display.
4) Post the value of gdb-debug-log to me (it may be large and is not of
   interest to the list).

The ^Z^Z markers that GDB outputs are characters that are processed by the
process-filter and are not related to ^Z typed from the keyboard which is
bound to the command suspend-frame.
