Comment 23 for bug 1390016

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.
