Hi,

I tried to experiment with HSA on recent upstream kernels [1][2], but instead it seems I ran into are some DC wiring(?) problems with Kaveri:

The primary display seems to work, etc, but the secondary display does seems connected anymore. I did not experienced the same problem on ubuntu 4.13 kernel when dc enabled (using the same boot options). I may saw some DC output wiring bugs (try to connect to wrong components) and patches somewhere related to kaveri, but I did not found again. Any suggestions how to fix it? THe kernel logs are attached.

Hardware: ASUS A88XM-A + A10-7850K

Software: Ubuntu 16.04

4.15 kernel comes from (using ukuu): http://kernel.ubuntu.com/~kernel-ppa/mainline/

4.13 kernel comes from ubuntu package.
