Have you tried custom install of 14.9.2 and uncheck usb filter and iommu? I also uncheck CCC and gaming evolved. Runs stable and smooth so far.14.9 working good in my machine (except for the random flicker in desk with couple of tabs open but i have that flicker in all of my 280X tested..)... 14.9.2 throw me A LOT of troubles with USB ports.
What's your process with DDU? Even using it I had horrible black screening with 126.96.36.199.9.2 is going great for me with two 290x with the help of DDU of course
you are uninstalling all amd software and drivers before rebooting into safe mode right? then use ddu to do its thing and while your at it manually delete the amd folders and can run cc cleaner before installing the new driver as well.What's your process with DDU?

Usually I just open DDU... it asks to reboot to safe mode, I let it. It does it's thing... I reboot when it's done and install drivers. Then reboot again.
Do you get a green checkmark at the end of the installation? It seems like no matter what I do I always get an error saying the driver is already installed.
