This file:
http://www.mjmwired.net/kernel/Documentation/power/basic-pm-debugging.txt Has some tips on suspend debugging.
In case you don't get a backtrace or isn't sure which module caused it,
the most used technique is to try to isolate the module which causes
the problem, one way to do it is to try the following:
1. Remove half of your modules
2. Try to suspend
3. Try to resume
4. If resume has worked, then the problem is in the last group of
removed modules
You can also try to boot with init=/bin/bash and initialize the
services by hand, trying to suspend before each initialization.
