Details

suspend2 2.2.7.4 removes its procfs support
in favour of a newer sysfs interface. This is in beyond2.2 and beyond3.

It's now located at: /sys/power/suspend2

echo "" > /sys/power/suspend2/do_resume
will not do it, as sys seems to ignore the empty echos,
echo 1 > /sys/power/suspend2/do_resume
works however

To facilitate this new setup, the following needs to be added to the resume
hook:

if [ -e "/sys/power/suspend2" -a "x${resume2}" != "x" ]; then
echo ${resume2} > /sys/power/suspend2/resume2
echo 1 > /sys/power/suspend2/do_resume
fi

It might be a good idea to leave the procfs setup there for people with other kernels, as 2.2.7.4 isnt 'officially' on 2.6.17, I backported for fixes.
This task depends upon

This is fixed in mkinitcpio svn. If /sys ignores the empty echoes, maybe echo "x" > do_resume would be enough?

I apologize for this - I've been super busy and haven't had the chance to fix a few bugs in mkinitcpio. I gave brain0 svn access so he could fix the resume issue. If you guys want, you can generate a new tarball (see the top level scripts that make life easier) and then just upload a new package (iphitus, you may want to toss it into testing first if you do not have current access).

Tonight I _swear_ I will sit down and hammer out a few bugs.

@iphitus: have you tried this? I can't try it, as suspend2.2.7.4 is quite unstable, but someone on suspend2 irc claims that the empty echo works for him.

Ok, I tried with a vanilla kernel with 2.2.7.4 and it worked (after I fixed another issue). I commited it to svn http://phraktured.net/initramfs/mkinitcpio/hooks/resume
