Package: linux-image-2.6-amd64
Version: 2.6.18.dfsg.1-13etch1

Debian Etch (up to date)
ifenslave-2.6 1.1.0-6
module-init-tools 3.3-pre4-2
ifupdown 0.6.8

I'm trying to setup two bonding interfaces with different settings (mode 0 and
2).

I followed the documentaion at
/usr/src/linux-source-2.6.18/Documentation/networking/bonding.txt

/etc/modprobe.d/bonding:
alias bond0 bonding
options bond0 -o bond0 mode=0 miimon=100
alias bond1 bonding
options bond1 -o bond1 mode=2 miimon=100

This didn't work because of the -o option. I found a debian bug
report regarding the -o option:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=270903#5

Next I tried the syntax that module-init-tools permits.

/etc/modprobe.d/bonding:
install bond0 /sbin/modprobe bonding -o bond0 mode=2 miimon=100 downdelay=200
install bond1 /sbin/modprobe bonding -o bond1 mode=0 miimon=100 downdelay=200

This was working with the 2.6.21 kernel from backports.org which I was
using at that time. The modules were loaded during boot time and ifup was able
to setup both bond interfaces with different options just fine.

Next I went back to 2.6.18, because of some other problems with the
2.6.21 backports kernel.

Now the bond1 interface is not configured properly and I get some
error messages during boot time.

Interface bond0 was setup correctly. But bond1 gives errors.

On screen I see some additional messages:

If I try this on the command line it's also not working.

# modprobe -v bond1

All of this is working with the 2.6.21 kernel.

I don't know if it's a kernel, module-init-tools, ifupdown or ifenslave-2.6
problem, but the only part I have to change to get this running is the kernel.
I still can boot 2.6.21 and everything is ok.

At the moment I don't see any way to setup two bonding interfaces with
different options and kernel 2.6.18.


/etc/network/interfaces:

# The loopback network interface
auto lo
iface lo inet loopback

# client lan
auto bond0
iface bond0 inet static
        address 192.168.1.5

thanks for the detailed description.
