I have a fresh CentOS 6 installation on a Dell R310 server with a Broadcom BCM5716. The onboard NIC is causing the boot to hang for some reason.

Welcome to CentOS Linux
Starting udev: udev: starting version 147
Boardcom NetXtreme II Gigabit Ethernet Driver bnx2 v2.0.23b (Feb 01, 2011)
bnx2 0000:02:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16

That's it... then it just hangs / freezes. If I disable the NIC via the BIOS settings, CentOS boots fine.

I've downloaded and installed the latest driver from Broadcom's website. Any ideas?

we have a very similar centos 6 issue with a broadcom 5754. I wonder if this will be the same issue ? - Keeping an eye on this one – Sirex Mar 1 '12 at 10:47
Just a little update -- I've spent so much frustrated time trying to get this working on various linux distros that I just went out and bought a new Intel Pro Server NIC. Worked like a charm with CentOS 5 and 6 -- no hassles. Definitely worth the $150. – DJ Tarazona Jun 17 '12 at 21:15
ditto :( same outcome here – Sirex Jun 20 '12 at 2:44

This question is a bit old now, but I came across it and thought I'd mention that we also had issues with this NIC on-board a Dell R710. Here's a link with some things you might try:

A colleague ended up resolving it with a combination of these steps.


  • Update the card's firmware
  • Get the latest Broadcom driver
  • Disable MSI; i.e. add 'options bnx2 disable_msi=1' to /etc/modprobe.conf and reboot.

+1 Firmware, it's always the firmware. – Chris S Jun 6 '13 at 13:11

Try to move it to another slot. If it does not help file an RMA with your vendor.

update: Then try to reset the BIOS settings. If it does not help contact your vendor

Can you elaborate? Another slot as in PCI slot or something? If so, unfortunately this is the onboard (embedded) NIC on the motherboard. – DJ Tarazona Sep 14 '11 at 15:44

I see this behavior alot with HP and ICO servers (ICO = local HW vendor). We usually solve it by either disabling all but one interface in BIOS or connecting all LAN ports with a switch so they have a link.
