* One if the used-to-be-hot Intel wireless issues is slowly going away as a result of
  a firmware update
* the i9xx GEM code is a high riser compared to the last report
* in general, networking is relatively high this report
* the long-fixed ext3 issues seem to still be with us

It would be useful if this warning dumped out some DMI BIOS information 
or something, so we could see what systems/boards this was commonly 
happening with..
