Could you enable omapdss debug by adding 'omapdss.debug=1 debug' in
your bootargs and share logs?

I'm not 100% sure what you mean for mmount -t debugfs debugfs
/sys/kernel/debuge to do here?
Do you mean to halt the kernel after suspending, but before resuming? If so,
how would I go about doing this?
I'd asked for reboot or power off as you have done below. The suspend
path looks okay, I asked for the power off to see if there was a
dss_runtime_get() was called at the wrong time by some interrupt while
suspending.
One difference between the shutdown and suspend logs is that we don't
see the prints 'omapdss DSS: dss_save_context' and 'omapdss DSS: context
saved', that seems a bit fishy.
I'm not sure how to go ahead from here. We haven't seen this on OMAP4,
and I don't think I have tried this on OAMP3. Maybe Tomi has more ideas.

If I just reboot or poweroff I get the following...
