I tried swsusp again (using the supplied script). Looked like
it successfully deconfigured everything, but never actually
suspended the machine (or maybe it did but then woke up immidiately?).
What logs should I look at to tell what was actually happening
and where it went wrong?
Also, is my understanding that swsusp is using suspend-to-disk (S4)?
Is there a way to use S3 and what is it good for?
thanks much for your help.
Fedor.
