--- Comment #86 from Mark Millard <markmi at dsl-only.net> ---
AMD wants to RMA the CPU for the Ryzen7 1800X PC that
I (sometimes) have access to.

So once the logistics are worked out and arrangements
made I will be out of the Ryzen testing process again.

Once this starts it could be a month or so before I'd
again have access.

FYI: with 13813 built so far the only
SIGSEGV/SIGBUS types have errors under
kern.sched.steal_idle=0 have been the 2
/compat/linux/usr/bin/gcc related SIGSEGV's.
There have been 37 failures overall. Some
are tied to not finding files so I've no
clue if those are tied to the odd problems
with such or not. But most are tied to
source code issues. A few failed to fetch.

The FreeBSD context for these tests is:

# uname -apKU
FreeBSD FBSDx6411SL 11.1-STABLE FreeBSD 11.1-STABLE  r322596  amd64 amd64
1101501 1101501

This is as a guest in a VirtualBox virtual machine
under Windows 10 Pro. 8 "processors" assigned in
VirtualBox. Around 50 GiBytes of RAM assigned.
