X.org screen

I've just tried kernel 2.6.37-rc6 and Intel HD graphics driver seems to be
totally broken - see the attached photo.

When I tried to switch to a text console - the screen became entirely black and
I couldn't switch to the broken X console any longer.

The computer was not hanging, but X server froze completely.

I have:

Kernel 2.6.36.2 works fine here.
