I only tested Bonaire. I can test Cape Verde if needed.

Crap, I already wanted to check back with you if that really fixes your problems.
Thanks for the info, this crash also only happens on CIK doesn't it?

Sorry to tell you the bad news. This patch doesn't fix the hangs on my machine.
I tested drm-next-3.16 from Alex's tree. I also switched copying from SDMA to CP DMA, which hung too.
I also tried this:
git checkout (the problematic commit): 6d2f294 - drm/radeon: use normal BOs for the page tables v4
git cherry-pick (fixes): 0e97703c - drm/radeon: add define for flags used in R600+ GTT 0986c1a5 - drm/radeon: stop poisoning the GART TLB 4906f689 - drm/radeon: fix page directory update size estimation 4b095566 - drm/radeon: fix buffer placement under memory pressure v2
Then I tested both SDMA and CP DMA copying. Both were unstable.
Testing was done with piglit / quick.tests.

When we set the valid bit on invalid GART entries they are loaded into the TLB when an adjacent entry is loaded. This poisons the TLB with invalid entries which are sometimes not correctly removed on TLB flush.
For stable inclusion the patch probably needs to be modified a bit.
