With intel_iommu=on in command line, GPU hangs at
boot, after which, the entire machine freeze happens.
I managed to retrieve logs by using "linux=single" -
it helps to avoid the full machine freeze sometimes
(maybe because X doesn't start then), but its still
a blank screen.
intel_iommu=on,igfx_off fixes the problem but I guess
this will not allow to pass-through the video card,
is this correct?

There are a few similar reports in this bugzilla,
but please note that my dmesg ends with Oops. So
probably it gives more info.
