Stack trace from coredump
New backtrace with debugging turned on. It appears that the issue is a NULL pointer dereference in r600_resource_copy_region (dst). In compute_memory_promote_item, pool->bo is NULL (which is what 'dst' is for r600_resource_copy_region). Created attachment 134061 [details]

When I run 'clpeak --global-bandwidth' I get: [benji@benji-pc clpeak]$ ./clpeak --global-bandwidth Platform: Clover Device: AMD CAYMAN (DRM 2.50.0 / 4.13.0+, LLVM 6.0.0) Driver version : 17.3.0-devel (Linux x64) Compute units : 12 Clock frequency : 880 MHz Global memory bandwidth (GBPS) float : radeon: Failed to allocate a buffer: radeon: size : 1073741824 bytes radeon: alignment : 4096 bytes radeon: domains : 4 radeon: flags : 4 radeon: Failed to allocate a buffer: radeon: size : 1073741824 bytes radeon: alignment : 4096 bytes radeon: domains : 4 radeon: flags : 4 Segmentation fault (core dumped) And in dmesg: [55959.960796] clpeak[16731]: segfault at 1c ip 00007f3d77e5a42a sp 00007fff93152570 error 4 in pipe_r600.so[7f3d77d53000+1c2000] The clpeak compute-* and kernel-latency tests work fine, and transfer-bandwidth fails with a (I believe) unrelated error message, seemingly due to me running Linux-git.
