Hi,
I recently added a R7 260X to my system. While the card works with 3.13 its supposed work much better with 14-rc. This is not the case. My system is unstable without radeon.dpm=0 which was the default in .13. Here are some extracts from the logs of the latest fun with dpm enabled:

The above type of errors repeat hundreds of times and eventually the display freezes (this box does not have a serial console and it did not check with ssh)
When X started I did notice some corruption. There are sets of two rectangles about of a height of 2 or 3 mm, width of 25m or so with a second about a cm below. The often occurs in chomium especially when scrolling. Runing the unigine-sanctuary or unigine-tropics demo/benchmark programs also produce the above problems and eventually stall.
The problem is reproducible - I am not that familiar with gpu problems though, what else will help debug this?
Please file a bug at https://bugs.freedesktop.org (Product: DRI, Component: DRM/Radeon) and attach your dmesg output and xorg log.
Filed as bug 75992
Let me know if you want me to test anything or if more info is needed.
TIA Ed
