Subject: Re: screen goes blank when loading gma500_gfx (atom D2500)

Hello again

It's been about 2 months since I sent the original debugging output.  Today I tried
out 3.14 kernel.  And this one behaves quite similarly, screen goes blank right
when loading gma500_gfx module.  Here's the dmesg from a freshly booted system
after doing

  modprobe drm debug=6
  modprobe gma500_gfx

with a monitor connected to VGA port (before loading gma500_gfx, it displays the
regular text console):
