Thanks, good to hear that the issue is fixed in the latest 3.18. Still wondering which commit actually fixed... It's a bad bug, so better to be fixed in the released kernel. I made a KMP containing a few possible backport fixes for openSUSE 13.2 kerne. Could you give it a try with openSUSE 13.2 kernel again? The KMP is found at OBS home:tiwai:bnc904932/radeon repo.
