Thanks! It changed the behavior of 2-socket G4 as well but that context now reports starting only one of the 2 CPUs and things do not go well from there. For example, USB2 fails and it basically hangs up before the login prompt (but it does check the root file system). It even reported something about NUMA domain 0 in the messages that I saw go by. Before, 2-socket died much earlier. But it is not getting to a status where I have any control/access. Of course, so far as I know, nothing has fixed the "kernel sometimes zeros user space pages that it should not" problem (even when sitting idle). So, ultimately, 32-bit powerpc FreeBSD is not sufficiently useful on any of the machines, other than via chroot on a powerpc64 FreeBSD machine. Anyway, I've a bunch of SSDs to update so the basic problem does not reappear if I grab another one. =3D=3D=3D Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
