Just to check the versions. steve@moose 5 0 % fgrep "\$FreeBSD" /sys/i386/include/smp.h /sys/i386/i386/mp_machdep.c /sys/i386/i386/mpapic.c ~/ 3:26pm /sys/i386/include/smp.h: * $FreeBSD: src/sys/i386/include/smp.h,v 1.53 2000/08/06 00:04:02 tegge Exp $ /sys/i386/i386/mp_machdep.c: * $FreeBSD: src/sys/i386/i386/mp_machdep.c,v 1.118 2000/08/06 00:04:02 tegge Exp $ /sys/i386/i386/mpapic.c: * $FreeBSD: src/sys/i386/i386/mpapic.c,v 1.40 2000/08/06 00:04:03 tegge Exp $ I've just copied the smp.h into /usr/include/machine as well, but now I can't seem to build anything at all, so it's possible I screwed up somewhere (although the newer panic below does indicate I managed to build a kernel with the new versions at least because the Changing APIC ID line only appears in the newer files I think..) =-= Panic Information : Changing APIC ID for IO APIC #0 from 0 to 16 on chip panic: can't control IO APIC #0 ID, reg: 0x00000000 mp_lock = 0000000a; cpuid = 0; lapic.id = 01000000 Uptime: 0s [ Machine freezed ] Anyway, I'm just about to cvsup down a completely clean source tree. Any ideas which I should go for - i.e. which might give me working SMP ? So... which should I try: HEAD, RELENG_4 (again) or wherever RELENG_3 is now ? [I'm open to all ideas on this one, as I find using one CPU on this box for what I need to do a little too slow for most things.] Tia, Steve To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
