Hmm... If there is a bug in kerneld, so that it dies when it loads a module,
there might be a schedule() at the wrong moment...
If someone with the problem has the opportunity to check if kerneld has
died immediately after the "Aiee" message, that might give me some input
for a bug-hunt in modprobe and/or kerneld.

Try the included patch.
