problem with intel 82576 and e1000 driver   
I just installed 6.4.1 on a Xeon system with dual 82576 Gb ethernet controllers. The e1000 driver loaded fine that gave 
me wm0 and wm1 devices. However networking doesn't work (plugged in our network, DHCP failed). 

I then connected the system directly to a working laptop, and  here are the ping behaviors:

if I initiate ping from the laptop, nicinfo shows all packets and bytes received OK, but no increment on Tx packets and 
bytes.

if I initiate ping from the system, nicinfo shows all packets and bytes transmitted OK, with some increment on the Rx 
packets and bytes but less than the number transmitted.

greatly appreciate any input on this.

It sounds to me as though interrupts are not working. Please can you
post the output from 'pci -v' on the system. Also, please check the BIOS
to see if there is an option to turn off Plug 'n Play.

Thanks, Hugh.

Thanks for the reply. Yes, the PnP OS was disabled in the BIOS. Attached is the output of pci -v

RE: RE: problem with intel 82576 and e1000 driver   
The pci output looks fine. Have you tried starting the network driver
with different interrupts?

Eg. io-pkt-v4 -de1000 irq=11,pci=0

Try various interrupts in the "irq=.." command line argument and see if
any of them work, This will start a driver on only the first interface.
If you want to try the second interface use "pci=1".

You might also try slaying io-usb and see if that makes any difference.

Re: RE: RE: problem with intel 82576 and e1000 driver   
I tried to load the driver with various irq settings, and it didn't work (failed to give me wm0/wm1 devices). I won't be
 able to slay io-usb since i need the keyboard, there is no network so i won't be able telnet. I guess i can try the 
serial terminal...

Does Windows or any other O/S run on this machine? If so, can you see
what interrupts are being used for the Ethernet adapters.

Re: RE: RE: RE: problem with intel 82576 and e1000 driver   
i just installed Suse Linux enterprise server 10 SP2 on another partition. The driver coming with the installtion didn't
 work either, I had download the new intel igb src for 82576 and make install to make the network finally work. Here is 
the info in dmesg, so it's using the message interrupt that QNX doesn't support yet

We will be supporting MSI in a future release.

Re: problem with intel 82576 and e1000 driver   
I think this has something to do with the incorrect (redirection table) settings of the IOAPIC in my 5520 northbridge. 
Interrupts from a PCI-X to PCIe bridge connecting to that northbridge is not being forwarded to the CPU either. So far 
only the interrupts from the ICH10 southbridge are being served.
