Comment 316 for bug 1690085

For me, Ryzen 7 1800X (acquired in late April 2017) on ASRock X370 Taichi with 2x 16GB (non-QVL) Kingston 9965669-019.A00G unbuffered ECC RAM (banks 2+4) on be quiet! Dark Power Pro 11 80plus 650W, is stable out of the box since BIOS 4.60 (2018/3/6) with default BIOS settings (except for SVM = enabled) on Ubuntu 16.04 and linux-image-hwe-edge 4.13.0.36.37. The previous BIOS version 4.40 (2018/2/9) also worked with a default Linux kernel image and without kernel parameters after setting the new BIOS 'current' option to the non-default 'full current' value.
So it just took a year and the follow-up generation to be released, yeay.
