Hi,
Thanks for constantly tolerating my ignorance. I git-cloned the
latest PM tree available and booted my 3430 LDP board with ldp
defconfig configuration. Now the problem regarding hanging of machine
after some small interval is solved but when I done 'echo mem
>/sys/power/state' it gives error to suspend,
This is log for it,
'/ # echo mem > /sys/power/state
<6>PM: Syncing filesystems ... PM: Syncing filesystems ... done.
done.

I searched similar problems on mailing list, in which suspend log
contains exactly which process could not be stopped as reason to
suspend failure. But in above log, I could not interpret such a
reason.
Could anyone please help me with this?
