This does not cause any troubles for me, but makes me wonder why it
happens, excerpt from vmstat -i -a:
irq16: 0 0
irq17: 0 0
irq18: 0 0
irq19: nvidia0 6310688 79
irq20: nve0 ohci0 3684463 46
irq21: pcm0 ohci1 75931 0
irq22: ehci0 0 0
irq23: 0 0
So, IRQ 16-18 and 23 are free, but IRQ 20 and 21 are shared between two
Is this something with the way my HW is wired ?
Or is this something with the way BIOS and ACPI tables are configured ?
Or is this something suboptimal with our ACPI and/or APIC code ?
