cat /proc/interrupts shows:

0: 180 0 IO-APIC-edge timer
1: 2510 0 IO-APIC-edge i8042
7: 0 0 IO-APIC-edge parport0
8: 1 0 IO-APIC-edge rtc0
9: 0 0 IO-APIC-fasteoi acpi
12: 618156 0 IO-APIC-edge i8042
14: 17818 0 IO-APIC-edge ata_piix
15: 0 0 IO-APIC-edge ata_piix

43: 81457 0 PCI-MSI-edge eth0 <======
So IRQ 43 is real assigned IRQ ??
