Broadcom BCM5716 Hangs on CentOS 6 Boot

  • 772

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?

  1. 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.

    Summary:

    • 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.

  2. 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

  3. 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.
