--- Comment #1 from Ming-Wei Shih xmingske@gmail.com --- I have the exactly the same issue here.
radeonsi + llvm 3.6 gives the exact same error while radeon (and llvm 3.6 installed) or radeonsi + llvm 3.5 never had any issue.
One remark though, it is possible to launch genymotion with the radeonsi + llvm 3.6 combinbation if one tries many times, sometimes it takes 3~5 retries and sometimes 30+. Once started it seems stable.
