>Description:
My system has/had 2 cards trying to use IRQ5.  One was a PCI sound card (which BSD did not recognize on boot), the other was a 3c509 network card.    Dmesg showed that both cards were loaded onto IRQ5.  However, vmstat -i did not list any cards as using IRQ5.  This caused me some headaches when I was trying to figure out why my networking wasnt working correctly.  I removed the sound card and rebooted, then vmstat -i showed IRQ 5 in use by driver ep0.  It seems like vmstat was confused due to the conflict.  Note that it did not show "mux" for IRQ5, it simply was not listed!
>How-To-Repeat:
Unsure.  My system does show IRQ9 as a mux, so perhaps you need 2 cards, one of which is an "unknown PCI card".  Another clue could be that the PCI card was unknown and the 3c509 card was using ISA.  Also note that even my BIOS attempted to map them both to IRQ5, WinXP remaps the 3c509 card to IRQ11...

 Matt,
 
 vmstat -i display is AFAICT correct for FreeBSD systems running
 RELENG_6 and RELENG_7.
 
 sample output:
 %vmstat -i
 interrupt                          total       rate
 irq1: atkbd0                       12092          1
 irq9: acpi0                           67          0
 irq14: ata0                        28678          2
 irq16: pcm0 bge0+                1139032         99
 irq17: ohci1 ohci*                     9          0
 irq18: ndis0                      224216         19
 irq21: fwohci0                         4          0
 irq23: ohci0 ehci0                 75022          6
 
 Of course, this output is not produced on a system with mixed PCI /
 ISA cards (but that sounds like a bad idea to have PCI and ISA cards
 sharing an IRQ).
 
 Do you see this problem on recent releases of FreeBSD? If not, can we
 close this PR?
