@gduperrey Skylake-S Xeon here w/o patched bios, works fine so far.

edit: double checked /proc/cpuinfo, seems the ucode update is applying correctly, so, yeah, it worked.

just joining the crowd of "seems fine"

@MichaelCropper I don't think that's entirely fair-there are plenty of homelabbers that purely do it as a personal side project, even if few of them end up on xcp-ng.

I mean, I'm certainly one of them.

Bumping my lab to staging right now-if you don't hear back, assume everything works fine.
