I managed to look at messages from another machine running Linux and it is using APIC ID 6, so the BIOS is ok. It may be that it doesn't like the sequence of IPI's that we send. Although, we use the exact method recommended by the MP spec. Look in start_ap() and try disabling the second startup IPI (just use #if 0) to see if it works better. > On Mon, Sep 23, 2002 at 02:56:19PM -0400, John Baldwin wrote: >> *sigh*, except that we may need to change to using logical APIC >> ID's instead of physical ones at some time.
