dmesg output with drm.debug=3D0x1e log_buf_len=3D1M

Hi,

I have two monitors connected to my PC one via DVI and one via DP. The moni=
tor
connected via DP shows "frequency out of range" when some modes i=
ncluding the
preferred one are used. This happens in X and in the KMS framebuffer. For
example on the attached logs the preferred mode of 1680x1050 does not work
where as 1680x945 works perfectly fine.

Kernel: 4.4.11
Xorg: 1.18.2
xf86-video-radeon: 7.7.0

Last working kernel: 3.19
First broken kernel: 4.0

Here is the bisect info, the 4.0 release segfaulted in the radeon driver but
the change which broke this was before so I hope the bisect is right:

# first bad commit: [e55bca26188e45f209597abf986c87cc5a49894a] radeon/audio:
enable DP audio

After finding the bad commit I tried booting with radeon.audio=3D0 this mad=
e the
display work for 3.19 kernel with that commit but did not work for the 4.4.=
11
kernel.

Attached log files:
 - dmesg output with drm.debug=3D0x1e log_buf_len=3D1M
 - lspci -vv output
 - video card bios
 - Xorg.0.log
 - xrander --verbose output
