[Bug 576511] Re: ACPI causes computer to hang when connected to network

[YS1]

apport information

** Tags added: apport-collected

** Description changed:

  I am using Ubuntu 10.4 (but the problem probably exists since 7.10 at
  least). I use a broadband modem to connect to the Internet, to which my
  computer is connected via an ethernet (RJ45) cable.
  
  Steps to reproduce :
   1. Unplug ethernet cable from computer ;
   2. Turn computer on ;
   3. Boot ubuntu (2.6.32-21-generic) with acpi support enabled (ie. not explicitly disabled) ;
   4. When logged in, plug ethernet cable into computer.
  
  Result : the network-manager icon starts animating (to indicate
  activity), and the computer hangs after less than 1 second ; there is no
  response to any stimulus (except hard poweroff).
  
  This problem also arises if I prevent Gnome, its network manager and GDM
  to automatically launch and start the network manually.
  
- However, this problem does not arise if Ubuntu is booted with the
- options "acpi=off noacpi" added to the boot command.
