CentOS - Sep 2013 - Getting a do_IRQ: xx.xxx No irq handler for vector (irq -1), any ideas?

I setup a CentOS 6 server to use with KVM/QEMU, and I am getting the
following error a good bit, granted it doesn't seem to be causing any
trouble.   I figured I would post and see if anyone has any ideas on the
issue, or if I can just dismiss it.

If I look at my logging/dmesg, I see:

do_IRQ: 19.217 No irq handler for vector (irq -1)
do_IRQ: 3.178 No irq handler for vector (irq -1)
do_IRQ: 19.179 No irq handler for vector (irq -1)
do_IRQ: 3.220 No irq handler for vector (irq -1)
do_IRQ: 18.213 No irq handler for vector (irq -1)
do_IRQ: 18.79 No irq handler for vector (irq -1)
do_IRQ: 3.144 No irq handler for vector (irq -1)
do_IRQ: 18.201 No irq handler for vector (irq -1)
do_IRQ: 18.124 No irq handler for vector (irq -1)
do_IRQ: 18.160 No irq handler for vector (irq -1)
do_IRQ: 19.208 No irq handler for vector (irq -1)
do_IRQ: 3.147 No irq handler for vector (irq -1)
do_IRQ: 18.117 No irq handler for vector (irq -1)
do_IRQ: 3.103 No irq handler for vector (irq -1)
do_IRQ: 3.169 No irq handler for vector (irq -1)
do_IRQ: 18.201 No irq handler for vector (irq -1)


The machine is an HP ProLiant DL580-G5 series with 4x Xeon hexacore
processors installed, along with 32G of RAM at this time.  I am happy to
post more dmesg output if it's of any help.

Kernel version is:  2.6.32-358.18.1.el6.x86_64

I had this too.. Found this from googling

Re: No irq handler for vector CentOS 6.4

Stop irqbalance

The message can appear when IRQs are moved between CPU cores. We can stop 
the irqbalance service moving IRQs by turning it off with:

         chkconfig irqbalance off
         service irqbalance stop


Note that this will result in all interrupt requests being handled by a 
single CPU core, which may be detrimental to performance.

Had the same problem a month or so ago (you can see the thread in the
archives). It appears, from the many hours of googling I did, to be a
problem explicitly with HP servers.

Checked for BIOS updates?

My DL380 G7 had similar problems, and they went away after a recent BIOS 
upgrade.
