The stack I used was (base is Debian Testing): GPU: Hawaii PRO [Radeon R9 290] (ChipID = 0x67b1) Linux: ~agdf5/linux:drm-next-3.17-wip (calls itself 3.16-rc4?) libdrm: 2.4.54-1 LLVM: 3.5 RC1 libclc: Git:master/0ec7437d9c Mesa: Git:master/74e100affc + the three patches Marek named ("radeonsi: fix CMASK and HTILE calculations for Hawaii"; "gallium/util: add a helper for calculating primitive count from vertex count"; "radeonsi: fix a hang with instancing on Hawaii") and can be found on mesa-dev.
