Months ago when I started using Fedora 13 from Centos 5.3

perhaps six weeks ago the probability of a successful suspension
and subsequent wake up seems to be about 50%-60%.
My question is what can I check to gather evidence about what's
going on and how to fix it?
uname -r: 2.6.34.7-56.fc13.x86_64
Machine: Lenovo X200 Thinkpad.
No problems with suspend (to ram), ASUS Z84F,
2.6.34.7-56.fc13.i686.PAE, FWIW.
The first place to look when diagnosing suspend problems is /var/log/
pm-suspend.log. After that, look at kernel doc, http://
www.mjmwired.net/kernel/Documentation/power/basic-pm-debugging.txt and
follow links from there, as seems appropriate.
FWIW, its sometimes said that reporting kernel problems to Bugzilla is
a waste of time, as kernel developers don't pay attention to them. I
can testify that my recent eperience (a suspend problem, no less)
contradicts that. They are, in fact, very attentive.
