dmesg for e965b8ce4215ac2b22b23ffc8a8dfbae964b9496
I have a radeon r9 285 (tonga) and I'm trying to run dual DVI displays via the
new AMDGPU driver. The problem I'm having though is that the display connected
to the DVI-I output goes blank during drm initialization on boot, and
thereafter never 'recovers'. If I plug either DVI-D or DVI-I in individually,
however, and disconnect the other on a fresh boot, either outputs work just
fine. Additionally, dual displays do work if I use any combination of DVI-D,
HDMI, or DisplayPort; which leads me to believe that the problem has something
to do with how amdgpu is handling output to DVI-I or a hardware problem.
Hopefully it is not the latter.
Please let me know if there is anything I can do to help debug this problem!
I'm using Debian unstable, with the latest linux kernel compiled from git
mainline (e965b8ce4215ac2b22b23ffc8a8dfbae964b9496)
dmesg and Xorg log should be attached.</pre>
