** Description changed:

  Binary package hint: network-manager
  
  Distribution: Ubuntu 7.04 Feisty Fawn - Herd 3
  Hardware: Zonet ZEW2501
  Chipset: zd1211b
  Driver: zd1211rw
  
  Description: 
- Upon attempting to configure this wireless device with NetworkManager, the 
window disappears and NetworkManager returns to the system tray.  I am unable 
to configure this device because the window goes away in what appears to be a 
crash although it is still active in the tray and can be reopened.  'ifconfig' 
and 'iwconfig' both show the device and report not conflicts.  The system logs 
appear normal and I didn't find any unusual behavior.

  Attempted Solutions: 
  Believing it was a hardware conflict I have tried booting Ubuntu with the 
following additional parameters...
  "noapic nolapic"
  "noapic nolapic pci=noacpi" - disables IRQ11 used by the device and causes it 
to not appear
  "noapic nolapic pci=noacpi irqpoll"
  "acpi=off" - disables the device when used with any of the above parameters
  
  Steps to Reproduce:
  1.) Boot with Zonet ZEW2501 (zd1211b) in Feisty Fawn Herd 3
  2.) Click the NetworkManager icon in the top right
  3.) Select the wireless device from the list
  4.) Click 'Properties'
  5.) The properties dialog may appear briefly for a few seconds before all 
NetworkManager windows disappear.  Both the properties and the nm window 
vanish, but NetworkManager is still running in the system tray on the top right.
