Devin,

When you say "the LCD turns off then on with success", do you mean you actually see output/graphics on the LCD after the resume other than just the backlight turning on?

I mean I see output/graphics on the LCD after the resume. The touch screen works fine. I run the 3D Graphics -> Chameleon demo (OpenGL ES Demos) and 2D Graphics -> Moving Blocks demo. Both work fine.
Also the VPSS-M3 firmware seems to behave correct after the resume:
omap_gpio omap_gpio.0: completing resume
platform l3_slow.0: completing resume
platform mpu.0: completing resume
platform reg-dummy: completing resume
PM: Finishing wakeup.
Restarting tasks ... done.

The difference between the "core" test and the actual suspend should be something related to the VPSS-M3 firmware (/usr/share/ti/ti-media-controller-utils/dm814x_hdvpss.xem3).In the basic-pm-debugging.txt we have:
In particular, the "core" test allows you to test everything except for the actual invocation of the platform firmware in order to put the system into the sleep state.
The error that we have after resume is the same as just unload/stop the VPSS-M3 firmware, without running any suspend/resume test:
