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?
