 Hello.
 
 I found very strange behavior. Ñ‚ot for nothing that I work for a tester :)
 
 http://www.freebsd.org/doc/en/books/developers-handbook/kerneldebug-online-ddb.html
 - Here I found how to use kernel debugger (Ctrl+Alt+Esc).
 
 I added to my config-file next strings:
 options         KDB
 options         DDB
 options         KDB_UNATTENDED
 options         BREAK_TO_DEBUGGER
 I did the rebuild of kernel, installed it, rebooted the PC.
 
 After reboot I typed into console "ifconfig wlan0 create wlandev ural0"
 and ifconfig didn't hangs. Device wlan0 was successfully created.
 
 I commented this 4 strings --> ifconfig hangs, wlan0 wasn't created.
 
 It's very strange :)
 
 Now I'll rebuild kernel with this parameters, read "man ifconfig" and try
 to make workable wireless lan. I shall write you results. Thanks.
