I am not sure why it happens, but AU0828_RESOURCE_VIDEO is freed 3 times in the 
segment you posted and never assigned. It will take a while, but I will see if I 
can prepare a patch to help us.

I'm glad you were able to compile the revised patch. I hope we have as much 
success in making the driver work.
