ixgbe/udev mystery

[Thomas Bendler]

Hi @all,

I've setup a F14 box (minimal install) on a Supermicro server. So far, so
good. After some configuration (mainly automtic stuff done by puppet) and a
reboot I noticed that only the 1Gb network cards where configured but not
the 10Gb cards. I didn't even see eth2 and eth3 using ifonfig -a. A look
into /etc/udev/rules.d/70-persistent-net.rules shows only entries for the
1Gb cards:

# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single
# line, and change only the value of the NAME= key.

# PCI device 0x8086:0x1096 (e1000e) (custom name provided by external tool)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="00:30:48:d7:1c:9e", ATTR{dev_id}=="0x0", ATTR{type}=="1",
KERNEL=="eth*", NAME="eth0"

# PCI device 0x8086:0x1096 (e1000e) (custom name provided by external tool)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="00:30:48:d7:1c:9f", ATTR{dev_id}=="0x0", ATTR{type}=="1",
KERNEL=="eth*", NAME="eth1"

So I've added the 10Gb cards manually (from an Ubuntu installation on an
equal box):

# PCI device 0x8086:0x10ec (ixgbe)
 SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="00:1b:21:3b:6c:19", ATTR{dev_id}=="0x0", ATTR{type}=="1",
KERNEL=="eth*", NAME="eth2"

# PCI device 0x8086:0x10ec (ixgbe)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="00:1b:21:3b:6c:18", ATTR{dev_id}=="0x0", ATTR{type}=="1",
KERNEL=="eth*", NAME="eth3"

So I also added ifcfg-eth2 and ifcfg-eth3 to /etc/sysconfig/network-scripts
with something like this (real IP configuration will be done later):

DEVICE="eth2"
HWADDR="00:1b:21:3b:6c:19"
NM_CONTROLLED="yes"
ONBOOT="no"

Now the funny stuff starts, after the first reboot the devices eth2 and eth3
shown up typing ifconfig -a. After the second reboot the eth2 and eth3
interface disappeared again and I now see in dmesg:

Any ideas?
