GPU Intel i7 6700K
MB Asus Z170-A
Gentoo Linux ~amd64
Linux 4.15.2
Xorg 1.19.6
KDE 5.12.0

A few GPU hangs happened to me last days, seems related to kernel upgrade from
4.14 to 4.15, but not sure. Sometimes it does not really recover and leaves the
screen in frozen state so I have to reboot with SysRq. This time it recovered
successfully, I didn't even notice the problem until I looked into dmesg for
another reason.
