           Summary: [GM45] Macbook2,1 stopped working with kernel 3.5.x
                    (Ubuntu 12.10)
        QA Contact: intel-gfx-bugs at lists.freedesktop.org
          Severity: blocker
    Classification: Unclassified
                OS: Linux (All)
          Reporter: kees.bakker at xs4all.nl
          Hardware: x86 (IA32)
            Status: NEW
           Version: unspecified
         Component: DRM/Intel
           Product: DRI

After updating Ubuntu on my Macbook2,1 (that's the 13" white macbook) I am not
able to get a working display anymore. But when I boot the old 3.2.0 kernel it
is (more or less) OK. (I say more or less, because 3D Unity isn't working. I
had to switch to XFCE.)

In the update process I have installed development mesa packages too, but that
didn't help either.

With 3.3.x kernel it continues to boot until it logs in, but then both keyboard
and network are dead.

With 3.5.x kernel I simply get a black screen, and no keyboard, and no network.
I think it gets stuck very early in the boot process.

So, one of the changes from Linux 3.2.0 to 3.3.x are not working.

I'd be most grateful if someone could give a hint what to do next to figure out
what is wrong. Here is the lspci output for device. Let me know what else you
need.
