Otherwise, it also seems to somewhat randomly freeze over time. Reverting to 4.3.x resolves the issues.

Sounds like it could be the problem discussed in http://lists.freedesktop.org/archives/dri-devel/2016-January/098821.html .
Come to think of it, I did experience that one day but never again.
I am having similar issue on AMD HD 7870 GPU, openSUSE Tumbleweed, and Kernel 4.4.0-1.2. I cannot say for sure the trigger, however, once the screen locks requiring a password, the password field becomes disabled although mouse and keyboard remain fully functional. In fact, it would seem the entire lock screen becomes unresponsive to both mouse and keyboard, and CTRL+ALT+Backspace needs to be employed in order to restart the session.
Can you guys try reverting the commits referenced in http://lists.freedesktop.org/archives/dri-devel/2016-January/098823.html ? Alternatively, can you bisect?
I had planned to test reverting those commits, but after reading through the thread it seems those commits simply further exposed symptoms of a larger issue that I believe was fixed in http://lists.freedesktop.org/archives/dri-devel/2016-January/097880.html. I am running a 4.4.0 kernel with that patch applied and so far have not seen the issues I described. Although, ironically, on my first boot I had the stuck login screen as described in the thread.

Happens for me sometimes too. Just some minutes ago when I right clicked on the network-manager icon the whole desktop froze more or less. I could move the mouse pointer some times but nothing was clickable. Could switch to tty1 but even that was super-slow recognizing keyboard inputs. Needed to strg+alt+2xbackspace to kill X. After that everything fine. Latest openSUSE Tumbleweed x64 on AMD APU A8 7600 Which logs do you need?

It ate up all my memory so the system needed to swap like crazy. It does only happen when the pc is idling for some time. And this happened with older kernel too. This morning it was the same cause (I remember kswapd was active), but I overlooked the memory consumption in top - sorry - my bad. So no problem here. Maybe its chromium related. I use firefox. I can later check if I can reproduce with chromium on 4.4, I am currently on 4.2 kernel
I have been running a patch radeon module (the reverted commits mentioned) on 4.4.0 kernel and have not seen the issues. See this for the specific revert patches applied: - https://build.opensuse.org/package/show/home:tiwai:bnc962535/radeon I'd suggest that Franklin tests it since we have spoken in IRC and see the same symtoms.
I tried again with 4.4.0 Tumbleweed on my APU system. I can not trigger the problem here. Resizing chromium and snapping to the edges etc. all works. Tried every kwin combination of EGL GLX and openGL 3.1 2.0. So APU Systems may have never been affected (or the mesa-update 11.1.1 yesterday evening helped).
