All I can think of is virtualbox, but I'm almost certain I did not have
virtualbox loaded (i.e. modules disabled so they wouldn't load) for my first
test with wired ethernet (yes, I know that virtualbox modules are known
for causing problems).
Ah, yes, I had another out of tree module:
http://www.thinkwiki.org/wiki/Tp_smapi
(on thinkpad W500)
Module Size Used by
hdaps 13616 1
tp_smapi 23531 0
thinkpad_ec 12857 2 hdaps,tp_smapi
So, I suppose the next step is to reproduce without those modules loaded,
which I'll do next.
Thanks,
Marc
