[solved]no IP/network after system failure, DHCP DD-WRT

Hi,

Recently the root file system (ext2) on the flash drive was corrupted, (due to transmission-daemon's status/log write operation I would say).

Have tried using fsck to repair file system and it fixed several errors.

Now the Pogo E2 could not boot into the system correctly (no ip showing in the router, can't access via network).
So what could I do to rescue it ?

here's the netconsole log

if boot without the Debian installation, there seems to have many bad blocks in the NAND, should I concern?

Ok, I was able to rescue the system by doing the following steps:

modify /lib/udev/rules.d/75-persistent-net-generator.rules change the eth to Eth

# device name whitelist
KERNEL!="Eth*|ath*|wlan*[0-9]|msh*|ra*|sta*|ctc*|lcs*|hsi*", \
					GOTO="persistent_net_generator_end"

change the /etc/network/interfaces file, edit it from a dhcp config to a static ip config:
(was dhcp on the debian and assign static ip from the router).

auto lo eth0 
iface lo inet loopback 
# iface eth0 inet dhcp 

iface eth0 inet static 
address 192.168.1.100 
netmask 255.255.255.0 
broadcast 192.168.1.255 
gateway 192.168.1.1

Also change the hostname in /etc/hostname.

This combination works, I don't know which step saved it.
