Kernel version : 3.4-rc1 Driver name :: bnx2 Error while loading the broadcom module - "modprobe bnx2" [ 3617.496683] bnx2: Broadcom NetXtreme II Gigabit Ethernet Driver bnx2 v2.2.1 (Dec 18, 2011) [ 3617.497475] bnx2 0000:01:00.0: eth0: Broadcom NetXtreme II BCM5709 1000Base-T (C0) PCI Express found at mem f6000000, IRQ 28, node addr 00:25:9e:d3:7a:1d [ 3617.498330] bnx2 0000:01:00.1: eth1: Broadcom NetXtreme II BCM5709 1000Base-T (C0) PCI Express found at mem f8000000, IRQ 40, node addr 00:25:9e:d3:7a:1e [ 3617.662526] bnx2: Can't load firmware file "bnx2/bnx2-mips-09-6.2.1b.fw" The firmware provided with 3.4-rc1 is bnx2-mips-09-6.2.1a.fw and the file referred from source file bnx2.c (path :linux-3.4.0-rc1/drivers/net/ethernet/broadcom) is "#define FW_MIPS_FILE_09 "bnx2/bnx2-mips-09-6.2.1b.fw" The source file (bnx2.c) in Kernel 3.2.12 is pointing to "bnx2-mips-09-6.2.1a.fw". Reverting the MACRO FW_MIPS_FILE_09 to this value, it works. fw version 1a or 1b is correct?
Just for reference, this was discussed: https://lkml.org/lkml/2012/4/18/142
if it is RHEL 6 1.add_drivers+="bnx2" - add this line in /etc/dracut.conf 2.Take the initramfs backup 3.Run dracut –f - to build the initramfs image 4.reboot This will fix the isse.
