what's the status of suspend-to-disk on ARM? The most recent discussion I found is: http://lists.linuxfoundation.org/pipermail/linux-pm/2012-November/034997.htm...
with no replies at all. Is anyone still working on that? Anyone got it running?
I tried the patch above (on top of LTS 3.4) and got stuck forever, the last thing on the console was:
root@omap5:/sys/power# echo disk > state [ 2015.641540] PM: Syncing filesystems ... done. [ 2015.666870] PM: Preallocating image memory... done (allocated 16957 pages) [ 2016.062011] PM: Allocated 67828 kbytes in 0.38 seconds (178.49 MB/s)
Any hint how to debug that?
I know it is still broken and I had discussion with Kevin in past regarding that. See below.

Hi Guys,
As discussed during connect about "HIBERNATION support for ARM platforms", this is my last mail on this, almost a year back, where i tried my best to get relevant answer from Amit.
Probably he missed all my mails then, but this might be a good starting point for this discussion as i did some testing on hibernation earlier.
I think the reason that ARM sub-arches are not setting things up is because ARM has never supported hibernation in mainline.
The most recent patch to add basic support[1] references the various discussions on what is needed and still missing.
