I've got the same problem with iwl4965:

** Summary changed:

- iwl3945: Wireless can't be activated after disabling kill switch
+ iwl3945 | iwl4965: Wireless can't be activated after disabling kill switch

** Description changed:

  Normally, the wifi kill switch of my Dell D620 is enabled because I
  don't need wifi often. If the system was booted with an enabled kill
  switch, then I can't reactive the wireless interface any more. Only a
  reboot with deactivated kill switch enables the interface again.
  
         description: Wireless interface
         product: PRO/Wireless 3945ABG Network Connection
         vendor: Intel Corporation
         driver = iwl3945
  
  This problem didn't occur on gutsy (which the closed source driver).
+ 
+ iwl4965 suffers from the same defect.
