Status of this bug in mainline didn't change. However, there are
patches to fix this issue:

  1. http://marc.info/?l=e1000-devel&m=125659409119946&w=2

Works -- interface is brought up properly.  However, kernel warns
about two allocation failures (and succeeds in thrid attempt).

Patches to make warnings appear every 10th failure have been
presented.  What this basically means for me is that failure message
would pop up every 5th suspend-resume cycle.

(Patch has a typo that needs fixing: s/struct cbs/struct cb/)


  2. http://marc.info/?l=e1000-devel&m=125637894721936&w=2

Works without any warnings.  Sadly, patch is far more intrusive.

Thanks.
