[Buildroot] Buildroot + Raspberry Pi B: eth0 issue

[Sylvain LG]

Hi,

I've built a Raspberry Pi B system with Buildroot (board/raspberry).

At first boot, network was fine. But after a reboot command, eth0 is not up
at boot and fails with this error:

Starting network...
> [    2.046886] usb 1-1.1: new high-speed USB device number 3 using dwc_otg
> ip: SIOCGIFFLAGS: No such device



Here comes some logs related to USB from dmesg command:

/etc/network/interfaces:

auto lo
> iface lo inet loopback
> auto eth0
> iface eth0 inet dhcp



If I log into the system, I can use the command ifup eth0 and it works!

# ifup eth0

 If I shutdown the system, it may work at boot time... or not, after
several retries.
ifup eth0 works everytime by hand.


What do you think about it?
It seems to me that hardware is not yet detected at network init time.
