CentOS - Dec 2011 - Unplugging DVI causes Disabling IRQ #11

I have some new PC hardware I'm using with the Intel H67 chipset.  I
created a bzImage I use for a PXE environment for a recovery mode,
installing OS images, etc.  The new mobo doesn't have a VGA port but
instead DVI.

Everytime I unplug the DVI cable it seems to cause "Disabling IRQ
#11".  After that the PC is basically unusable.  The /proc/interrupts
shows that hdd, usb, nic, RAID controller for some reason all share
the same interrupt.  What the heck?

I tried booting with acpi=off and the bios doesn't seem to offer any
IRQ/PnP options.  Am I missing a specific driver in my bzImage for the
H67 chipset or any ideas of what I could try next?  It's been a sad
day.

bash-2.05b# cat /proc/interrupts
           CPU0
  0:   15185951    XT-PIC-XT        timer
  1:          4    XT-PIC-XT        i8042
  2:          0    XT-PIC-XT        cascade
  7:         75    XT-PIC-XT        ehci_hcd:usb2
  8:          1    XT-PIC-XT        rtc
 11:    2090574    XT-PIC-XT        ahci, ehci_hcd:usb1, eth0, rr172x

I even see a similar error on a fresh CentOS 5.7 install:

Thanks for any help.

I posted this as a bug to redhat's bugzilla I think in January of 2011.
