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.

Or use hibernate -v4 from a root terminal to see any error messages.

  I ended up emerging hibernate-script and it runs great.  I added a few
tweaks to hibernate.conf.  Here's what it looks like...

TryMethod disk.conf
Distribution gentoo
OnResume 00 setfont lat1-10
DownInterfaces auto
UpInterfaces auto
UseSysfsPowerState disk
PowerdownMethod shutdown

  As for pm-utils...

Why the bleep can't some programmers go to the bathroom without invoking
hal and dbus?  They're hard-coded dependancies for pm-utils.  I've
managed to keep hal and dbus (and java and pam) off my machine, and will
continue doing so.  If I had a bunch of money lying around, I'd hire some
programmers to seriously slim down Firefox while I was at it.  There is
no reason a browser should need an SQL database.

  Nothing obvious in dmesg when I tried manually shutting down.  The
listing showed the system shutting down, and then starting up.  No
warnings, let alone errors.
