apport information

** Tags added: apport-collected driver-b44

** Description changed:

  When I boot my laptop in some cases wlan works fine, but in other cases
  (20%) wlan does not work. This behaviour appears since I updated Ubuntu
  to version 11.04. In earlier versions of ubuntu wlan worked without
  problems. I am using a Dell Inspiron 9400 with Intel 3945ABG wireless
  card. The security of my wlan is wpa2-psk.
  
  As attachment I upload a syslog extraction.
