With:
* Mesa 10.5.0-devel (git-6171131)
* LLVM 225080
* Kernel: 3.19.0-rc7-13532-g1b7a4a0 (same)

No lockups

So this is either a LLVM or Mesa Issue.

I will now compile latest Mesa with LLVM 225080 and see if that works.

Given that this is hardly a DRI/Radeon issue.. where should I move this bug?
