Hi,

I just tested v4.11-12441-g56868a4 on HP xw6600 with radeon graphics,
and I'm seeing the following WARNING triggered constantly.

I have not seen this earlier e.g. with the distro kernel 4.10.13-200.fc25.x86_64

$ lspci|grep -i amd
60:00.0 VGA compatible controller: Advanced Micro Devices, Inc.
[AMD/ATI] Curacao PRO [Radeon R7 370 / R9 270/370 OEM]
60:00.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Cape
Verde/Pitcairn HDMI Audio [Radeon HD 7700/7800 Series]
