I think it may be a bad interrupt controller, and was planning to tackle interrupt routing for it, as I think MacOSX routes all non-IPI interrupts to core 0. I do have a 2.3GHz machine of the same family that runs FreeBSD perfectly, though, so my motivation is lacking right now. - Justin On Jan 14, 2013 7:21 PM, "Krzysztof Parzyszek" wrote: > Hi, > > I just got a Mac G5 (PowerMac11,2 Dual-core G5 2.0GHz) and I installed > FreeBSD 9.1 on it (using a 9.1-release iso image).
