I have released an initial alpha release for a x86
(uniprocessor) Linux kernel patchless debugger under
the GNU GPL at savannah.gnu.org. Project is called
kmdbg. First debugger implemented is a remote serial
debugger.
It is just a simple interrupt/exception/syscall
interception scheleton and may have a lot of errors
(or not work at all) although it worked for me with
kernel 2.4.XX, 2.5.24.

This is just fantastic. I'm glad to see someone ran with the ideas of
patchless kernel debuggers as described in the Adeos paper and the likes.
There are definitely interfacing opportunities with the Adeos work
that's already been done using a kernel patch. Having both Adeos
as a kernel patch and as a patchless nanokernel is now really within
our reach.
Kudos to Miguel :)

There has been another one at http://pice.sourceforge.net for a long time.
Unfortunately it only works for 2.2/i386/UP properly. Fixing it for 2.4
is not that hard however.
