This is acceptable. I originally believed that this situation meant that there was NO physical path on the board from 8254 to APIC pin #2, and that the statement to the contrary (ie that there is) in the mptable meant a defective mptable. I now suspect that the issue might be that something in the motherboard chipset is improperly set, and if we could determine what that was we could program it and skip the redirection of the 8254 thru the PIC (not APIC) as we now do in this case. However, none of the SMP systems I have access to exhibit this behaviour so I can't be the one to chase it. -- Steve Passe | powered by smp@csn.net | Symmetric MultiProcessor FreeBSD To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
