But it was just as early as far as where the message appeared. I have not tried powerpc64 FreeBSD head -r357419 on an old PowerMac. (Yet?) Note: PowerMacs do not take input to the bd> prompt this early. Note: Both of these PowerMac reports are for kern.vty=3Dvt , because for kern.vty=3Dsc the output stopped before any backtrace showed. =3D=3D=3D Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
