Hi Tony,
I use omap2plus_defconfig.
I have been working with BeagleBone Black (bbb) for hibernation on this branch:
http://git.linaro.org/git-ro/people/sebastian.capella/linux.git hibernation_3.13_russMerge
I ran into a few minor issues on Russ' branch for bbb that I had to work
around. In the end it worked fine, but I know I had to add some entries
in the dts files at least for it to work.
On bbb I'm resuming from initramfs by echoing the hibernation
swap device onto /sys/power/resume during my initscript, but before
remounting the partitions. You may need to do similar.
You will have to change power managemennt -> hibernation to on in
menuconfig.
I can help more, please let me know what you have and how you'd like to
set it up.
Thanks!
Sebastian
