I ment are they both on 14, not 15. (Sorry not feeling good the last few
days and kinda working in a cloud).   Ok, so in theory, even though the BIOS
is saying "You guys are on IRQ 6" or "You guys are on IRQ 13".... as long as
lscpi -v and cat /proc/interrupts shows the devices not sharing and IO-APIC
I should be ok?
