This interrupt sharing may caused by interrupt routing in ACPI code.
What's the vmstat -iv on both w/ and w/o ACPI interrupt routing?
Yes they are a bit different.
OK, please test following commit on master:

Nope. Still the same, but they are now on different irqs. I noticed
however that my drm0 doesn't get set up with acpi interrupt routing
turned on.
With acpi interrupt routing:
interrupt total rate
irq0: clk 31844 248
irq4: sio0 0 0
irq7: ppc0 1 0
irq9: acpi0 0 0
irq10: ral0/rl0/vge0/ehci0 7536 58
irq11: fwohci0/pcm0/rl1/atapci0/uhci0/uhci1/uhci2/uhci3 9982 77
irq14: ata0 37 0
irq15: ata1 0 0
irq19 46 0
irq21 6525 50
irq192: swi_siopoll 0 0
irq195: swi_cambio 0 0
irq196: swi_vm 0 0
irq197: swi_taskq/swi_mp_taskq 0 0
Total 55971 437
Without:
interrupt total rate
irq0: clk 331584 331
irq4: sio0 0 0
