interrupt statistics

[Mike Tancsa]

Speaking of which, why is it some devices are not always present
(same with systat -vmstat)

eg on one machine
v2% vmstat -i
interrupt                   total       rate
stray irq7                      2          0
hifn0 irq10                 15680          0
fxp0 irq11                 259067          2
mux irq15                  378597          3
atkbd0 irq1                     1          0
sio0 irq4                     178          0
clk irq0                 11466632         99
rtc irq8                 14677398        127
Total                    26797555        233

yet on another,
offsite# vmstat -i
interrupt                   total       rate
fxp0 irq11               29547828         61
mux irq15                  453753          0
sio0 irq4                     177          0
clk irq0                 48204090         99
rtc irq8                 61701185        127
Total                   139907033        290
offsite# 
offsite# dmesg | grep hifn
hifn0 mem 0xe9802000-0xe9802fff,0xe9801000-0xe9801fff irq 10 at device
0.0 on pci1
hifn0: Hifn 7951, rev 0, 128KB sram, 193 sessions
offsite# 

How come the hifn does not show up ?  I have noticed this with other
devices as well
