Comment 29 for bug 1774950

Here are a few thoughts:

I've tested other Debian-based distributions whose display managers are Gnome or XFCE, running the 4.15 kernel, and the same problem persists. Perhaps we should look wider than just solutions for Ubuntu. For example, Fedora seems to have the same problem, as does Arch Linux ( https://bugs.archlinux.org/task/57511 and https://bugzilla.redhat.com/show_bug.cgi?id=1551262 , respectively). I just notice that almost all links above are directly related to Ubuntu, and that could be limiting.

Has anyone looked into the solutions for Spectre and Meltdown? Perhaps the latest solutions have caused problems with the Intel hardware.
