OpenBSD Gets Mitigated For Meltdown CPU Vulnerability

A few days back FreeBSD 11 stable was mitigated for Meltdown (and Spectre vulnerabilities), which came more than one month after these nasty CPU vulnerabilities were disclosed while DragonFlyBSD was quickly mitigated and the first of the BSDs to do so. While OpenBSD is known for its security features and focus, only today did it land its initial Meltdown mitigation.

Some FreeBSD Users Are Still Running Into Random Lock-Ups With Ryzen

While Linux has been playing happily with Ryzen CPUs as long as you weren't affected by the performance marginality problem where you had to swap out for a newer CPU (and Threadripper and EPYC CPUs have been running splendid in all of my testing with not having any worries), it seems the BSDs (at least FreeBSD) are still having some quirks to address.
