swsusp freezes

swsusp freezes

[Rajsekar]

I am using 2.6.8-rc4-mm1 kernel at my home.  When I try to swap suspend
(either using swsusp or pmdisk) it figures out how much memory is required
and all and then sometimes freezes giving a backtrace.  I am interested in
debugging this problem.  Can someone tell me the basic things required
(softwares and some docs if any) to debug such kernel codes.  This is my
first venture into debugging kernel codes, so I am very much a newbie.

Thank you

You could start by reading Documentation/BUG-HUNTING and 
Documentation/oops-tracing.txt

Also, you could post the Oops to the list so other people can take a look 
at it. Including info on your hardware, kernel version etc is often 
useful. Take a look at 
http://www.kernel.org/pub/linux/docs/lkml/reporting-bugs.html for details 
on what it is usually a good idea to provide (also take a look at the 
other documents linked from that page).
