            Bug ID: 88301
           Summary: Kernel 3.16 boot hang with i915 driver on GMA3150
           Product: Drivers
           Version: 2.5
    Kernel Version: 3.16.5
          Hardware: Intel
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: blocking
          Priority: P1
         Component: Video(DRI - Intel)
          Assignee: intel-gfx-bugs at lists.freedesktop.org
          Reporter: mfld.fr at gmail.com
                CC: intel-gfx-bugs at lists.freedesktop.org
        Regression: No

After switching from kernel 3.14.14 to 3.16.5, the i915 driver does not work
any more and hangs the kernel boot with a blank & black screen.

Hardware:
  Asus eeePC 1001PX
  Platform NM10 / ICH7
  Graphic chip GMA3150

Problem insulation:
  Remove i915 from kernel .config and rebuild: no more kernel boot hang

Workarounds:
  1- Keep i915 out and replace by generic VESA driver (degraded resolution)
  2- Keep same kernel configuration and downgrade to 3.14 line
