I'm having really good luck with the kernel patch attached to this

Since applying that patch, I did three poudriere runs to build the set
of ~1700 ports that I use.  Other than one gmake-related build runaway
that I've also seen on my AMD FX-8320E, I didn't see any random port
build failures.  When I was last did some testing a few weeks ago,
lang/go would almost always fail.  I also would seem random build
failures in lang/guile or finance/gnucash (which uses guile during its
build) on both my Ryzen and FX-8320E machines, but those built cleanly
all three times.

I even built samba 16 times in a row without a hang.
