I was having just about the same issues as @Marvex after installing the Indi to my revision 1D.something board. I belief it's not a firmware problem he experiences.
My advice: Take out the mobo completely (don't leave it in the case as I did first), put it in a level surface and give the Indi a good push. That's what helped me.
What's left are some "fishes" that disappear after some minutes, indicating a warming issue.
