I'm debugging the kernel with gdb over a serial port. Breakpoints and
stepping through code works great, except for the fact that once the
kernel is running, I can't seem to use Control-C to stop it. Is there
a keypress or other interactive way to break a running kernel?
Thanks,
Dave

Dave,
There are a great number of kgdb patches in the wild. You would help
us out a lot if you were to name the one you are using. If you are on
then 2.5 kernel I suggest you check out Andrew Morton's area and use
that one.
If you are using the one from source forge on a 2.4 kernel, there is a
mailing list for it that can be found at the same sourceforge site.

Here's the output from gdb --version:

Does that help?
Thanks,

NO :( It is the KGDB patch that you are using that is of interest
here, not the gdb program.
