Hey, MS bashing! Can I join in?
Now, wouldn't it be sacrilege to post to any technical list with
something like Outlook?

That's output from the kernel bootup-sequence, he's seen it and is
asking if that is normal behavior/output.
To answer the question, yes, it is perfectly normal to see that.
That's just the kernel describing how the PCI IRQs are set up. You
have nothing to worry about.

I think it's the "disabled" that worries.

No, i worried about the " (IRQs *7)" format.
I never seen this before....
I searching the bottleneck of my system, and simply found these lines.
I have another question:

How can i avoid this?
(all irq on CPU 3)
The echo /proc/irq/#smp_affinity # >smp_affinity
Has no effect. :-(
I tried it with kernel irq load balancing is on and off.
But nothing is changed. :(

Thanks for the answer!
I ask that because i newer seen this format befor: "[LNKA] (IRQs *7)"

ACPI PCI Interrupt Links are a way to connect device interrupt
wires to (an assortment of) interrupt controller IRQ inputs.
The "disabled" simply means that particular link
isn't being used -- likely because the link is used
only in another mode (eg. PIC vs APIC mode), or because
there is nothing attached to that interrupt wire.
The kernel will complain loudly if a device references
a disabled link, as it would be a BIOS bug.
The '*' is the IRQ that the link is currently using.
Later on in the dmesg you will be able to see
at device probe time which links are used by
which devices.
In PIC mode we don't balance the IRQs between
links -- though you could enable it with "acpi_irq_balance".
The reason we don't is because too many legacy BIOSs
fail when we do.
In IOAPIC mode, acpi_irq_balance is enabled by default.
This process assigns devices to IRQs, and the idea of
'balance' here is to minimize sharing of the same IRQ
wire between multiple devices.
This has nothing to do with the run-time balancing
to target a given IRQ at a specific CPU.
