Updated to latest Fedora 29 kernel today and the problem is still evident. Linux s0.home 4.19.4-300.fc29.x86_64 #1 SMP Fri Nov 23 13:03:11 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

Switched to the nvidia drivers today and no issues, so looks like it is probably nouveau related? sudo dnf config-manager --add-repo=https://negativo17.org/repos/fedora-nvidia.repo sudo dnf -y remove \*nvidia\* sudo dnf -y install nvidia-driver nvidia-settings kernel-devel nvidia-driver-libs.i686 # wait for the kernel driver to build in the background (top) then... sudo reboot
I ran into the same problem since I upgraded to 4.19. I've been using the 4.18 kernel to get my work done. I just tried the 4.19 and 4.20 vanilla kernels packaged for Fedora, and the problem is still there. I've been suspecting the Spectre mitigations until I found this bug -- I now tried the proprietary nvidia driver, and it seems to have made the problem go away. In case it helps, I have a GTX1080 founders' edition.
