Logfile
Switched from catalyst to amdgpu, Kernel 4.2 and Kernel 4.3 with powerplay
fixes crash, wenn modesetting is enabled (which just has to be, to get
everything working..)
When booting without modesetting no Kernel Panic occurs, but just nothing else
works really good...
I'm using Archlinux with mesa/llvm etc build from git.
Kernel 4.2 is Archlinux vanilla kernel, 4.3 is build from

Log files are attached.I've tried with disabled/enabled Iommu, it think this
Log is with disabled Iommu.</pre>
