I never intended to use it other than testing if I can create working image that has working Intel HD Graphics for Valleyisland.  Then I tried latest poky/meta-intel combination since dvhart/bsp-ng was merged there.

ok, this is report #2 of this. I'm firing up some tests here to see
if I can reproduce it.

You shouldn't need your mod to make it work .. so I'll dig out what
is happening.

Or am I doing something wrong again? I had to comment out that line to be able to use my own kernel version on later tests.
