Hi,

I am porting TuxOnIce to Freescale's i.MX6(Cortex A9) platform running
Linux - 3.0.35. The hibernation works fine but after resume, the display is
corrupted. I found out that a block of memory(nearly 128MB) is used by the
GPU and is carved out of kernel address space using memblock_remove(). I
think this region is not included in the hibernation image. Is there a way
to include the reserved memory in the image, so that the display contents
are restored back after resume?

Thanks and Regards,
Akshay
