Running long lasting OpenCL kernels (e.g. GROMACS with a system of many atoms) using kernel 4.8.15, Mesa git, and LLVM git on Kabini APU: vendor_id : AuthenticAMD cpu family : 22 model : 0 model name : AMD Athlon(tm) 5350 APU with Radeon(tm) R3 stepping : 1 microcode : 0x700010b with GPU: 00:01.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Kabini [Radeon HD 8400 / R3 Series] [1002:9830] causes GPU lockups like: [338584.980657] radeon 0000:00:01.0: ring 0 stalled for more than 10351msec [338584.980811] radeon 0000:00:01.0: GPU lockup (current fence id 0x00000000000827c1 last fence id 0x00000000000827c2 on ring 0) [338585.484633] radeon 0000:00:01.0: ring 0 stalled for more than 10855msec [338585.484789] radeon 0000:00:01.0: GPU lockup (current fence id 0x00000000000827c1 last fence id 0x00000000000827c2 on ring 0) [338585.988632] radeon 0000:00:01.0: ring 0 stalled for more than 11359msec [338585.988787] radeon 0000:00:01.0: GPU lockup (current fence id 0x00000000000827c1 last fence id 0x00000000000827c2 on ring 0) Machine does not hang. This is reliably reproducible. Any other info I can provide?
