So, atpic works ok, but amd64 + APIC doesn't work in either UP or SMP, but i386 + APIC does work fine, and all the interrupts are routed identically, etc. What happens if you do 'hw.physmem=2g' and boot an amd64 kernel with APIC? -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.org
