Hi,

AFAIK one of the biggest benefits of 6.5 having APIC support is that the limit of 0xf interrupts is gone so we don't 
have these issues with shared interrupts (added latency, etc.) any more.

What is the expected behaviour of a system with enabled APIC support? Somewhere I read that the probability of having 
shared interrupts gets smaller - why is it not completely eliminated?

On my test system, with APIC support I see indeed much less shared interrupts (cool!), but I still see interrupt vector 
0x10 used for io-usb AND io-display. Is this expected?
