 Yes, proposed watchdog fixes the crash. After booting into system and
 attempt to open Network preflet I have observed new "Network" combobox
 filled with lot of empty menu entries with "wlan" icon at the right.
 At the next boot this preflet was not opened at all and syslog was filled
 with messages:


 {{{
 KERN: wlan_control: 9235, 76
 }}}

 Corresponding syslog is attached.
