Hmm, I modified your config to add smc911x support so I can have an
nfsroot, added selector/code for my board(based on omap3beagle.c) and
brought it up on my hardware, but I'm not sure if its working correctly.
It does look to pause in the suspend sate, and comes out when I hit a
key on the console, but the messages don't look quite right as
core_pwrdm and per_pwrdm state they didn't go into state 1 (full log
attached):
omap3530# echo mem > /sys/power/state
PM: Syncing filesystems ... done.

Is this expected?
