I haven't tried with kernels earlier then 2.6.7, when I ran into the 
problem there I tried upgradeing to see if it fixed it and it didn't.


here is /proc/interrupts with eth0 and eth1 in use
happy1-p:~# cat /proc/interrupts
           CPU0       CPU1

here is after doing ifconfig

 cat /proc/interrupts
           CPU0       CPU1
  0:     760722      31813    IO-APIC-edge  timer

syslog shows

There are two ways of constructing a software design. One way is to make it so simple that there are obviously no deficiencies. And the other way is to make it so complicated that there are no obvious deficiencies.
