Where can I get a copy of the debugger for 2.6 kernel for PPC
platform. Thanks.

There are a number of options:
KDB - Needs some extra patches from oss.sgi.com. One of the down
points is the Kernel has to run in single mode.
KGDB - Needs an extra patch from kgdb.sf.net. I dont think this one
can do PPC but it can do PowerPC with flatened device tree.
GDB - Bit messy to start up but can debug modules.

Oprofile - Can be used to profile the kernel usage, if that helps.
Strace - Can be used to find out what system calls a user mode program
does.

But in my humble opinion I got the best results out of the following
two methods:
Printk - Straight out printk s to dump debug data to the system log
and view it (after the fact) in dmesg.
BDI2000 - This is an excellent JTAG hardware debugger which can be
used to step through code. Bit expensive though, and need a JTAG port
on your board.

If you want more specific details on any of these, GOOGLE IS YOUR
FRIEND!
