Looking over both the Internet & in-kernel documentation for KGDB, KGDB documentation seems lacking and it's usage process can not easily be determined.

One good example, is the mixing of terms for "target computer" and other terminology for the destination and/or reciever can easily confuse users.

Proper documentation would completely define the two computers as:

X = computer for debugging kernel
Y = stable computer being used for GDB frontend


I also can't immediately get KGDB/GDB working over serial console tty.  I do have a completely working serial console over tty for debugging kernel loading, as well as an inittab entry.  Even disabling these on cmdline and inittab still proved KGDB non-functional here.


So, as a side not, likely I'll need to get it work through ethernet first or by some other means. :-/
