:please try out my kgdb changes which i imported from freebsd.  it 
:provides a new binary kgdb, thus gdb -k doesn't exist anymore.  it can 
:show all kernel threads and is better in unwinding over trap frames.
:
:i need feedback before i can commit this, so please check it out.

    The patch works for me.  It's showing the stack frames a lot better
    then gdb -k was before.

    I would say go ahead and commit it, Simon.  It is a definite 
    improvement.
