Broadcom BCM5716 Hangs on CentOS 6 Boot
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.
