It's been reported that less memory actually makes the PowerMac= G5 boot correctly. I'm trying to understand why Mark's SLB hack is necessary, since it should logically be necessary on any other AIM-architecture platfo= rm, including my POWER9, so I'm really confused. Unfortunately, my G5 no longer works, and actually died shortly before I committed the change that reporte= dly broke G5s. I was/still am hoping that someone could go beyond Mark's divin= g, and determine just why the APs can't handle SLB faults at that point in the boot process, because they really should be able to. kern.smp.disabled=3D1 should make any G5 boot correctly, but then you're obviously stuck with only a single CPU. --=20 You are receiving this mail because: You are the assignee for the bug.=
