[nslu2-linux] Re: Upgrade to Lenny from Etch

Just to report that I have just had the same problem -- udev reassigning eth0 to eth1 on upgrade to lenny.

Glad to find this post.

Commented out the udev rules, as suggested above, and on boot up it recreated a new one to use eth0. Everything fine from then onwards.

From /var/log/syslog:
Nov 22 23:06:30 debianslug kernel: [42949423.890000] eth0: MII PHY 1 on NPE-B
Nov 22 23:06:30 debianslug kernel: [42949424.160000] udev: renamed network interface eth0 to eth1

From 70-persistent-net.rules, after commenting out and rebooting:

# This file was automatically generated by the /lib/udev/write_net_rules
# program, probably run by the persistent-net-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single line.
# MAC addresses must be written in lowercase.

# Unknown net device (/class/net/eth0) (ixp4xx_mac)
#SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="00:13:10:d6:1e:a7", NAME="eth0"

# Unknown net device (/class/net/eth0) (ixp4xx_eth)
#SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0f:66:7c:dd:11", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

# Unknown net device (/class/net/eth0) (ixp4xx_eth)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0f:66:7c:dd:11", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

So, in summary, it looks like something from ipx4xx_mac is left behind. I think that I have used this USB disk on both this and a spare (backup) NSLU2 with etch installed. Unsure of exact history -- lovely thing about these things is that you set them up and then they just work...
The only problem I've ever had was with a power supply failure. Replacement from Maplins was fine.

Off topic - did the hardware mod. with an Atmel chip to auto power on after a power cut (I live in a village where we get one a week). V. straightforward, and well worth it.
