It looks like the offending commit is already reverted in lts-utopic -next:
a907233 Revert "drm/radeon: hold reference to fences in radeon_sa_bo_new" 72a5cff drm/radeon: hold reference to fences in radeon_sa_bo_new
I built a test kernel of -next, which will be the next release. The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1566727/
Can you test this kernel and see if it resolves this bug?
