I had the same last night (on the main mirror), but I think there
used to be more than one mirror site. Haven't tried since, and it
is irrelevant to this problem. ...

I asked on lwn, so far the consensus is that a lot of 32-bit x86 is
embedded and never gets updated anyway. Distros are gradually
dropping i686, AFAICS nobody has offered a potential fix - but there
is a PoC exploit at github which can apparently run on i686.
And for Meltdown, although AMD x86_64 is not affected, nobody has
offered a view on whether or not AMD i686 is affected.
There were some comments on the FreeBSD Questions list (for the
moment they do not have a fix even for x86_64) that they would hope
to fix i686 after x86_64 is fixed. But using FreeBSD, for someone
who understands linux, looks to be very painful. Another poster
said he *thought* the problem started with the Westmere generation.
