Hmm I am not entirely sure I understand what you mean. ifconfig output
is as follows:
a) with 'processor' loaded

One additional problem in debugging this is that it seems to be
depending on the local network topology, since I somehow cannot
reproduce it when downloading from machines on the LAN or when I have a
slow downstream connection (e.g. DSL).

Hmmm, I cannot see a difference between battery and ac. I will look into
it a bit more, though.
