Re: [issue352] SMP weirdness in 1.6.2-RELEASE

[Petr Janda <elekktretterr@xxxxxxxxxxxxxx>]

My server which is SMP, produces

APIC_IO: MP table broken: IRQ 15 not ISA when IRQ 14 is!
Programming 16 pins in IOAPIC #0
Programming 16 pins in IOAPIC #1
Warning: IOAPIC #1 pin 17 does not exist, cannot program!

in dmesg. I mean it  seems to work well as it should, but im just asking 
why this happens?

To Mike:
Ive seen that error before on one of the SMP boxes ive setup with 
DragonFly, have you tried updating BIOS?

In my opinion as long as it says CPU #x launched that shouldnt be a 
problem....
