Don't fall for this. The Linux-Kernel has been having IRQ-sharing for
quite some time now.

Look at mine; and I'm happily writing through this 'mess':

PCI: Found IRQ 10 for device 02:06.0
PCI: Sharing IRQ 10 with 00:1f.2
PCI: Sharing IRQ 10 with 02:06.1
PCI: Sharing IRQ 10 with 02:0f.0
PCI: Sharing IRQ 10 with 02:0f.1
PCI: Sharing IRQ 10 with 02:0f.2

Look how 'loaded' the IRQ 10 is here !

How about showing us your cat /etc/modules and ifconfig for a change
to the better ?
