Well, 4.x does mask level-triggered APIC interrupts, but I'm not sure the boot interrupt is the issue as people have tried to turn the boot interrupt off and that didn't help. :( I'm not sure why the interrupt aliasing is occurring. I do wonder if it happens on Windows or other OS's and nobody notices. -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.org
