Re: Suspend - no resume

Hi

thanks for all the suggestions - i everything.

after noticing that it wouldn't suspend without X either, i figured it
had to be something i still wasn't missing or not doing.

i had placed my suspend script for the initrd image creation
within /etc/mkinitrd/scripts and (to be sure - clutching at straws at
this point) in /etc/mkinitramfs/scripts/local-premount. it seems that on
running dpkg -i kernel-image-xxx.deb it wasn't executing the script and
adding the required echo > /proc/suspend2/do_resume to the initrd image.

i finally got it to work by creating the initrd image manually after
installing the new kernel with suspend2 enabled. so after installing i
ran mkinitrd on the newly installed kernel manually and all is now well.

the contents of my suspend2 script under /etc/mkinitrd/scripts is below

#!/bin/sh
cat <<EOF >>$INITRDDIR/script
if [ -z "\$noresume" ]; then # be careful with the 'dollar' sign
    echo > /proc/suspend2/do_resume
    umount -n devfs
    umount -n proc
fi
EOF

anyway, working now. thanks heaps for the suggestions. it was a big
help. whole process was a little untidy and messier than expected but
got there in the end.

has anyone had any issues with installing kernel images and having any
init scripts run for initrd?

anyway... thanks again.
