Two interface problem  
Hi,
I am using Bernecker computer with two integrated ethernet interfaces. When I connect this B computer to the switch like
 in attachment. Ping both of interfaces from PC computer, there is a strange behaviour of the system. When I remove 
LNK_2 interface en1 stops to respond for ping. When I remove LNK_1 connected to en0 with connected LNK_2 both interfaces
 stop to respond for pings. After restore of LNK_1 both interfaces star to respond for pings.
I do not have any clue what is going on. With both connected links connections work stable.
Regards, Marcin

Re: Two interface problem  
You cannot have 2 interfaces on the same subnet. If you want to do this,
you will have to start 2 instances of io-pkt.

Re: Two interface problem  
We also have a similar problem on or ppc freescale P1022 (dual core)
With one interface, no porblem
as long as we enable the 2nd interface ,  when we stress our server program, after minuts
the first io-pkt-v4-hc starts consumming  100% CPU of core 1
after a while the  io-pkt-v4-hc  of the 2nd interface consummes 100% of the core 2
And it's not a problem of conflicting addresses of the interfaces (subnet are totally distinct...)
