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
  Reporter: abitt...@opensuse.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


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.
