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)

<snip> 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.

Hi Mark, I am seein the same errors on many el6 machines (not HP) but based on Asus Sabertooth X79 workstation boards with Intel Core i7-3970X CPU's. . Steve
