I did some testing, and the problem is this:
If the networking-script (which enables rp_filter, ip_forwarding, syncookies
and does ifup -a) is ran _before_ loading network driver modules, then the
network
modules (e100) will load successfully without crashing. In this case the
interface is left unconfigured because the network driver is not loaded when the
networking-script is run.
But, if the e100-module is loaded first (before the networking-script is
ran, the normal case), then the domain0 kernel crashes while loading the
module..
So networking-script does something, which enabled the e100 module to load
without crashing.. any ideas?
