dmesg including xorg log

Using the 4.11-rc6 kernel on Mullins based laptop crashes xorg and hangs the system. Changing to a vt doesn't work but rebooting works with sysrq. I tried rc5, but the same happens there. Amdgpu works on my system with 4.10.

Attached is the dmesg log including the xorg log and crash. There is also a kernel oops message present in the log.


xorg 1.19.3

Seems this was a kernel configuration error. AMDGPU_CIK was not set, which caused the problem. Works as intended with the option set.
