Description Gabriele Paggi 2009-06-28 21:53:23 UTC
Description of problem:

Server HP DL180 with two "Broadcom NetXtreme BCM5722 Gigabit Ethernet PCI Express" NICs.
Both card are recognized by the OS and the tg3.ko module is loaded but I'm not able to bring up the second network interface.
The same exact NIC works on another server (same model) that is running Windows 2003 STD 32Bit.

Version-Release number of selected component (if applicable):

2.6.18-128.1.14.el5

How reproducible:


Steps to Reproduce:
1. ifup eth1
  
Actual results:

tg3 device eth1 does not seem to be present, delaying initialization.

Comment 1 Gabriele Paggi 2009-06-29 15:01:54 UTC
My apologizes. 
Mac-addresses were misconfigured in the ifcfg-eth[01] files. Modifying the two files according to what is reported by dmesg fixed this issue.

As a result of comment #1, I am going to close this as not-a-bug.
