<pre>@Damian, I had the same problems. My configuration is similar to yours: Radeon
7870, Linux 3.16.1, xorg 1.16, MESA 10.3 RC1 (fedora f21 branch).
After consulting <a href="https://wiki.archlinux.org/index.php/ATI">https://wiki.archlinux.org/index.php/ATI</a> it tried adding
radeon.dpm=0 to my kernel command line as a workaround. It solved the problem.
No more lockups. The system is now stable with the above configuration. Clearly
this has something to do with the powermanagement changes in MESA and the
kernel (there were no lockups with earlier versions of MESA)</pre>
