Note that 4.14.9 has caused a spate of issues, including inability to boot machines with CONFIG_MCORE2=y. Gentoo has masked it. See https://lkml.org/lkml/2017/12/28/64 and https://bugs.gentoo.org/642268. I was lucky and saw the message on LKML before rebooting. Very sloppy for a stable release.

It's a shame these things happen, but I guess it highlights the fact that CPUs that aren't commonly found in “developer machines” are basically the wild west as far as support goes. I had a similar problem with a recent glibc crashing on Atom chips - that was a bit harder to recover from, but I learned why Busybox is installed by default that day…

Given that the same bug is also present in Linus's tree, we are doing well with being "bug compatible" here :)

Anyway, seems to be a compiler issue, see the long thread. It's easy to work around at the moment (change compiler versions or change kernel build options), so there are known solutions at the moment.
