How do I get gdb to do this?  When I try to single-step I get the 
"invalid reply" message then gdb is basically hung.  I'm using gdb 
v6.1.  Also for reference, single-stepping works fine on the same 
platform using a old (~ 2 years) version of kgdb and a 2.4 kernel.  It's 
just the new 2.6 version of kgdb that I can't get working right.

Thanks in advance,
Lance
