Created attachment 128760 --> https://bugs.freedesktop.org/attachment.cgi?id=128760&action=edit Photo

Using Fedora 25 with Mesa 13 and LLVM 3.8 on:

04:00.0 Display controller [0380]: Advanced Micro Devices, Inc. [AMD/ATI] Venus XTX [Radeon HD 8890M / R9 M275X/M375X] [1002:6820] (rev 81)

identified as "AMD CAPE VERDE" by Mesa. Photo is attached. This is a dual GPU laptop (Lenovo Z51-70), main GPU being

00:02.0 VGA compatible controller: Intel Corporation HD Graphics 5500 (rev 09)

While corruption happens, dmesg | grep radeon does not show anything suspicious, just:

Should I test LLVM 3.9/4.0-git? Any other info that could be useful?
