[SOLVED] e1000e runtime suspend breaks shutdown

[Kaso_da_Zmok]

i was experiencing shutdown and reboot issues with my Dell E6400.
It was shutting down OK if i was at work while the laptop was in docking station.
But at home while connected only to wifi it never did.
after some investigation online i have landed on the e1000e bug

e1000e runtime suspend breaks shutdown
https://bugzilla.kernel.org/show_bug.cgi?id=36132

the bug was introduced in 2.6.38 and is still here with 3.2.1 and 3.2.2
so if the network cable is unplugged and you have Runtime Power Management enabled it will prevent the shutdown

so removing the e1000e before shutdown resolved my weeks long messing with kernel options.

my workaround was to create executable script that would be run by /etc/init.d/local
