Title:
  Disable network / Enable network makes system hang up for a while

Status in The Linux Kernel:
  Incomplete
Status in “linux” package in Ubuntu:
  Invalid

Bug description:
  This is like many others, a very old bug and it is still unsolved,
  although it is very easy to reproduce it. I am a young linux user, but
  I could see it in Natty, Oneiric and now I tested it in Precise, both
  with the standard kernel and the latest RC.

  uname -a
  Linux florin-Satellite-C650 3.4.0-030400rc5-generic #201205011817 SMP Tue May 1 22:18:19 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

  How to reproduce it:
  1. Click the Network icon on top bar
  2. Go to Disable network and press it
  See the system hangs up for half a minute or more. Nothing moves, not even the mouse pointer.

  
  Exactly the same when you Enable Network from that place.
