Title:
  3.2.0-77: networking extremely slow in Virtualbox (virtio-NIC)

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I've experienced a very slow network in the 3.2.0-77 kernel as guest
  Virtualbox (2.4.28). I'm using the virtio NIC.

  The vboxadditions have been recompiled for  3.2.0-77.

  Even connections to localhost are unbearable slow.

  With 3.2.0-76 network speed was "normal"
