--- Comment #6 from Victor Costan <costan at gmail.com> ---
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.
