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

[Gari]

Hi,

I have the same Bug but I have no SCSI elements and it hangs when I run "/etc/intit.d/networking stop" or restart.
I work with a resolution of 1920x1280 and when it hangs, is quite "curious", all my windows resizes to 1024 (or something like that), unity and app menus dissapear,  terminal windows los their focus, some windows can take the focus and you can interact with  then but not with the menus.
If I switch off the rj45 cable, then I can't turn the network On until I reboot or shutdown the whole system.

My pc is a HP ProBook 6555b

  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.
