dmesg for amdgpu on kernel 4.10-rc2

This is just to report a few errors with amdgpu in kernel 4.10-rc2 on my
laptop, featuring :

APU : AMD A10-7300 Radeon R6, 10 Compute Cores 4C+6G (from /proc/cpuinfo).
iGPU : 00:01.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Kaveri
HDMI/DP Audio Controller
dGPU : 01:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Topaz
XT [Radeon R7 M260/M265 / M340/M360 / M440/M445]
Xorg : 1.18.4, on Arch Linux

$(dmesg |grep -i amdgpu) is in the attachement k4.10-rc2_amdgpu_dmesg.txt.
In brief, there are errors related to UVD and IB with Kaveri iGPU.

I do have a normal X session, except that the laptop never suspends, and things
can then go as bad as corrupting the file system beyond recognition by Grub.

I am posting this information in the hope it can be useful to developers.

Regards.
