https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=235060 Justin Hibbits <jhibbits@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jhibbits@FreeBSD.org --- Comment #21 from Justin Hibbits <jhibbits@FreeBSD.org> --- Hi Curtis. 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 platform, including my POWER9, so I'm really confused. Unfortunately, my G5 no longer works, and actually died shortly before I committed the change that reportedly broke G5s. I was/still am hoping that someone could go beyond Mark's diving, 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=1 should make any G5 boot correctly, but then you're obviously stuck with only a single CPU. -- You are receiving this mail because: You are the assignee for the bug.home | help
