To není nic divného pokud je zapnut apic a/nebo MSI:

cat /proc/interrupts
            CPU0
   0:   26033737    IO-APIC-edge  timer
   1:      60422    IO-APIC-edge  i8042
   3:     129872    IO-APIC-edge  serial
   7:          2    IO-APIC-edge  parport0
   9:          0   IO-APIC-level  acpi
  12:     688026    IO-APIC-edge  i8042
  15:        114    IO-APIC-edge  ide1
169:     110165   IO-APIC-level  libata
177:    2280202   IO-APIC-level  ohci1394, nvidia
185:     251945   IO-APIC-level  eth0, Bt87x audio, bttv0
193:       3998   IO-APIC-level  VIA8237
201:          0   IO-APIC-level  ehci_hcd, uhci_hcd, uhci_hcd, uhci_hcd, 
uhci_hcd
NMI:          0
LOC:   26033199
ERR:          0
MIS:          0


Jinak se připojuji, chybu bych viděl taky jinde než v DMA...
