            Bug ID: 100800
           Summary: With KMS:No link with displayport and A6-3600 APU from
                    4.4.x to 4.11.0.rc8, unless nomodeset kernel boot
                    parameter
           Product: DRI
           Version: XOrg git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
          Assignee: dri-devel@lists.freedesktop.org

With KMS:No link with displayport and A6-3600 APU from 4.4.x to 4.11.0.rc8,
unless nomodeset kernel boot parameter


Please see my original distribution bugreport at
<https://bugzilla.opensuse.org/show_bug.cgi?id=1035240>

Tested with OpenSuSE Leap 42.2 (all x64) kernels 4.4.x up to 4.11.0.rc8 kernels

Hardware:
Motherboard: F1A75-V PRO by Asus, with AMD cpu/gpu/apu  all-in-one: AMD A6-3600
APU with Radeon(tm) HD Graphics

hdmi port on motherboard and on the same monitor with hdmi cable works and
produces link, same motherboard with displayport cable and ports and same
monitor at its displayport port gives no link, unless one uses the "nomodeset"
kernel boot parameter.

Thank you.
