Comment # 4 on bug 106544 from Leonid Maksymchuk

With my Radeon R9 Fury, I tested kernels down to 4.16.3 (latest version that
does not crash) and found this commit to be a reason for errors:

https://patchwork.kernel.org/patch/10354647/

I built kernel 4.16.13 with this commit reverted, and it works nicely without
errors in dmesg.
