My documentation:

I could not have any luck even with your doc. Am not sure what am missing. Some details are below.
The .config options/macros under kernel hacking are as below:
# Kernel hacking
.
.
.
CONFIG_KGDB=y
CONFIG_KGDB_CONSOLE=y
CONFIG_KGDB_THREAD=y
# CONFIG_KGDB_ONLY_MODULES is not set
CONFIG_KGDB_8250_NOMODULE=y
# CONFIG_KGDBOE_NOMODULE is not set
# CONFIG_KGDBOE is not set
CONFIG_KGDB_8250=y
CONFIG_KGDB_SIMPLE_SERIAL=y
CONFIG_KGDB_BAUDRATE=115200
CONFIG_KGDB_PORT_NUM=0
---> The CONFIG_KGDB_THREAD=y is not present in the .config even after the patches are applied. I have edited the lib/Kconfig.debug and enabled it. The GDB_CONSOLE macro in the kernel code is only related with mips, so didnt try for it.
My grub.conf is as below:
title Red Hat Enterprise Linux AS-up (2.6.9-34.EL)
root (hd0,6)
kernel /boot/vmlinuz-2.6.9-34.EL ro root=LABEL=/ rhgb quiet
initrd /boot/initrd-2.6.9-34.EL.img
title Linux-2.6.15.5-kgdb
root (hd0,6)
kernel /boot/vmlinuz-2.6.15.5-kgdb ro root=/dev/hda5 gdb gdbbaud=115200
savedefault
boot
Your doc doesn't speak about gdbserver. Isn't it required ?
Thanks
