I am getting zero interrupts for a new Digium TE134 Card on a new brand new Dell T40 server with the latest BIOS. Is there something that I am missing or is the card not compatible with Dell servers?

(cat /proc/interrupts ; sleep 1 ; cat /proc/interrupts) | grep -i wcte13xp0
16: 0 0 0 0 IR-IO-APIC 16-fasteoi
