It would be nice to check at /var/log/message to get more information about
what goes wrong when you suspend or resume. Is it a stock kernel? Maybe it
would worth using swsuspend2 (w/ a custom kernel), anyway there's things to
investigate before.

Also, what USB devices are you attempting to unplug? Are they devices that
you can safely unplug (mouse?) and some that freeze your system?
