--- Comment #22 from Timo Aaltonen <tjaalton at ubuntu.com> ---
You need to install the matching linux-image-extra package too, which has all
of drm/*.. that'd explain the boot hang.

I think the problem that OEM1&2 are seeing (and not OEM3) is due to the fact
that their first-stage installer uses a slightly older kernel (-34) which then
might(?) leave the hw in some state that after a reboot to the latest kernel
it'll fail with this issue. The gpu hang can't be reproduced after the second
reboot.. I'll try to synthesize that on my hw.

And I'll double-check if this is the diff the images have.
