Ok I'm going to address this issue.  You specified multiple issues in
your email.  I think it's better to split each issue into its own
posting.  It's simpler easier to work with one problem at a time and
also replies to postings on different issues don't get all garbled
up/confusing in archive searches.

Ok the echo trick isn't the recommended way to suspend to disk.  A
better way is to use "pm-hibernate --quirks" (pm-hibernate is from the
pm-utils packages).  The --quirks option will try to handle any, well,
quirks that are known with your hardware.  echo'ing to /sys/power/state
is a little more low-level and could be iffy on some types of hardware.

You should also check dmesg.  More than likely there is a kernel error
that explains why it failed to suspend completely.
