Hello list,
I know the subject has been already discussed on the list, but without
any real solution...
It seems that there is a real problem with the 12th Dell generation
poweredge and Wheezy about the Broadcom NIC.
In my case I'm using Dell R420 server and an up-to-date Wheezy.
During my test in our development network everything was fine.
Yesterday I decide to rack the server in your production network, and I
was unable to use the eth0:

Whereas the eth1 was working.
Then, I've decided to came back to your development network, (20km ...!)
with the server, and I was unable to reproduce. Everything is fine.
During kernel boot I always found this (in working and not working cases):
Jul 11 11:33:05 xxxxxxx kernel: [ 0.629277] pci 0000:02:00.1: address
space collision: [mem 0xdd000000-0xdd03ffff pref] conflicts with
0000:02:00.0 [mem 0xdd000000-0xdd03ffff pref]
I don't know if this can be related, and how to solve it.
Is anyone have suggestions ?
Many thanks
