Bug ID: 99326
Summary: Boot problem and White
dots/noise/speckling/shimmering/corruption on Radeon
HD6320
Product: DRI
Version: unspecified
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: major
Priority: medium
Component: DRM/Radeon
Assignee: dri-devel@lists.freedesktop.org
Reporter: mrj@advancedcontrols.com.au
A default Gnome install of either Fedora 25 or Fedora 24 (latest spin)
Workstation, on a machine with a Radeon HD6320 (AMD G-series T56N) graphics
chip running 1360x768@60Hz, has a display that most of the time is black on
boot (reboot required -- hangs?), but occasionally completes booting with a
display that all over shimmers with white noise, as seen in the following
video:

The problem has been traced to this Linux kernel commit
https://github.com/torvalds/linux/commit/ff0bd441bdfbfa09d05fdba9829a0401a46635c1
, made to fix Bug 95206.
Xorg logs and xrandr output seem to indicate the the same modeline is selected
after this commit is reversed, even though the boot and display problems no
longer occur.
The equivalent Red Hat bug is
