Some more info:
I prevented e1000e from being autoloaded and booted with the cable
unplugged.
T1:
Plug cable
modprobe e1000e -> Works
T2:
modprobe e1000e
plug cable -> Works not
rmmod e1000e
modprobe e1000e -> works not
unplug cable
rmmod e1000e
modprobe e1000e -> works
rmmod e1000e
unplug cable
modprobe e1000e
plug cable -> Works not
rmmod e1000e
unplug cable
plug cable
modprobe e1000e -> Works not
So if the module is loaded w/o the cable plugged it does not work. If
I unplug before unloading the module and then plug in before loading
the module again it works again.
Thanks,
tglx
