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: 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?

If you don't need the 2.2.1 driver I suggest you remove the kmod-bnx2 package from the first machine and fall back to the driver in the normal kernel package. /Peter -------------- next part -------------- A non-text attachment was scrubbed...
