[The stable/head mix seems to be a wrong idea: 11.2 gets past the SMP: messages just fine on the so-called G5 "Quad Core".] On 2018-Oct-8, at 5:14 PM, Mark Millard <marklmi at yahoo.com> wrote: > On 2018-Oct-8, at 1:27 PM, Justin Hibbits <chmeeedalf at gmail.com> wrote: > >> On Mon, 8 Oct 2018 15:37:43 -0400 >> Dennis Clarke <dclarke blastwave.org> wrote: >> >>> On 10/08/2018 03:04 PM, Mark Millard via freebsd-ppc wrote: >>>> On 2018-Oct-8, at 10:25 AM, Michael Tuexen <tuexen at >>>> fh-muenster.de> wrote: >>>>>> On 8.

To start on this I took enough from: http://ftp1.freebsd.org/pub/FreeBSD/snapshots/powerpc/powerpc64/11.2-STABLE/ to see if it would get past the SMP: messages that head is not reaching. It produced the SMP messages just fine and kept going past that point. So I tried: http://ftp1.freebsd.org/pub/FreeBSD/releases/powerpc/11.2-RELEASE/ and it did the same. 11.2-Release does not fail during the same activity as head (if it fails at all). So I'm not exploring the artifact.ci.freebsd.org stable-11 material that I listed. I may explore head via: https://artifact.ci.freebsd.org/snapshot/head/r*/powerpc/powerpc64/kernel.txz === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)home | help
