I just kickstarted a new machine with the latest CentOS 6.2 files, including kernel 2.6.32-220.13.1.el6.x86_64. It came up without network interfaces.
dmesg says:
bnx2: Broadcom NetXtreme II Gigabit Ethernet Driver bnx2 v2.2.1 (Dec 18, 2011) alloc irq_desc for 36 on node -1 alloc kstat_irqs on node -1 bnx2 0000:01:00.0: PCI INT A -> GSI 36 (level, low) -> IRQ 36 bnx2 0000:01:00.0: setting latency timer to 64 bnx2 0000:01:00.0: firmware: requesting bnx2/bnx2-mips-09-6.2.1b.fw bnx2: Can't load firmware file "bnx2/bnx2-mips-09-6.2.1b.fw" bnx2 0000:01:00.0: PCI INT A disabled bnx2: probe of 0000:01:00.0 failed with error -2
The firmware file is missing from /lib/firmware and the kernel-firmware rpm.
I found a copy of it on a Fedora site and dumped it into the right location, but it wasn't found after a reboot. Yet, it was found after a second reboot. Why is that? Is a rebuild of initramfs triggered somehow?
What I don't understand is: I have an identical machine that I installed under 6.2 a while back, and kept up to date, and it doesn't have this problem. However, it tells me it uses version v2.1.11 (July 20, 2011) of the driver, how is that possible?
