9.1-RELEASE-p1: em0: Could not setup receive structures

[mxb]

Hello list@,

I'm mostly active on OpenBSD-side, however I have several machines running fbsd with ZFS.

I'v recently upgraded(today) from 8.2-stable to 9.1-rel because of em(4) with the problem  <subject> on 8.2-stable.
However, my problem has not disappeared after mentioned upgrade.

I serve VMWare images from this machine.
