[Bug 1010045] Re: 12.04 hangs on shutdown deconfiguring network interfaces

[dseira]

Same problem with a ubuntu 12.04.02 on a VM under VMWare ESXi 5.1 with
several network interfaces. I also have an LDAP into the network. I've
tried by changing the timeout to the ldap but with the same problem.

If I execute the service networking stop; halt it works correctly; the
problem is rebooting.

  We only have this issue when a vm has multiple network cards assigned.
  When we do a manual "/etc/init.d/network stop; halt", the vm shuts down like expected.
