[CentOS] 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
