I know. I just wanted to point out that we probably don't want the patch 
in 2.6.27 in this form, users wouldn't like to have warning in their logs 
every time mutex is not acquired on a first attempt :)

We are currently running reproduction tests on affected machines to verify 
that this patch really fixes the root cause of this whole e1000e saga.
