Journald output radeon ring 0 stalled for more than XXX msecs

Hi, 
when grading a video with the new GPU-accelerated kdenlive frameworks branch I
encounter a GPU lockup when I add three effects to a clip simultaneously (White
balance(GPU), Saturation(GPU) and Deconvolution sharpen(GPU) ) and seek the
timeline. I already filed a bugreport here
https://bugs.kde.org/show_bug.cgi?id=346184 but I think the problem lies in the
driver rather than the program because trying the same on Intel hardware slows
the system but there is no crash / lockup. 
Fortunately I managed to recover the journal (is attached)
I hope you can help me. Thanks!

Hardware: 
HD 6970 (Cayman XT)

Software: 
Archlinux
Kernel 3.19.3
Mesa 10.5.4

Kdenlive stack: 
kdenlive frameworks git (PKGBUILD attached)
mlt 0.9.6 (PKGBUILD attached)
movit 1.1.3 GPU effects package (PKGBUILD attached)
