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

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:
irq 169: nobody cared (try booting with the "irqpoll" option)

Thanks for any help.
