<pre>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?</pre>
