Hi Caz,
Let me explain clearly.
I turn on KGDB setting on config file to build kernel 2.6.27.10. on target
machine, originally it was with CentOS5.2, as my menu.lst shown below,
default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title CentOS (2.6.27.10)
root (hd0,0)
kernel /vmlinuz-2.6.27.10 ro root=/dev/VolGroup00/LogVol00 rhgb
console=ttyS0,115200n8 kgdboc=ttyS0,115200
initrd /initrd-2.6.27.10.img
title CentOS (2.6.18-92.el5)
root (hd0,0)
kernel /vmlinuz-2.6.18-92.el5 ro root=/dev/VolGroup00/LogVol00 rhgb
quiet
initrd /initrd-2.6.18-92.el5.img
During my test, I use kernel 2.6.27.10 on target machine.
I ever tried to build the gdb-6.8 and gdb-6.8--Kgdblight from svn repository
on kernel 2.6.27.10 and CentOS5.2, kernel 2.6.18-92.el5, and fail by
"Nothing to be done for 'install-target'" and "Nothing to be done for
'install'".
That is why I decide to fellow the instructions on your website.
Any comments are all welcome.
Thanks,

Hello Nick,
Are you using gdb from rpm or from svn repository? Also are you using
2.6.18-92.el5 kernel or svn repository? I don't remember I still support
2.6.18-92.el5. I suggest trying gdb from svn repository and 2.6.27.10
kernel.
Have you seen boot message when you run minicom for your target?
