iwi driver

hello all,

since the last update dated
Sat Apr 22, (current),
the iwi driver does not work:
cannot change any achannel, no association!
the old version of the driver, works perfectly, i use it at this time.

/*	$FreeBSD: src/sys/dev/iwi/if_iwi.c,v 1.34 2006/03/12 18:54:40 damien Exp $	*/
/*	$FreeBSD: src/sys/dev/iwi/if_iwi.c,v 1.27 2006/01/29 12:03:03 damien Exp $	*/

the nic is onboard of a s5 Sony.
The UPDATING says nothing so, perhaps is it a driver problem.
Please can you tell me something to do about this?

thanks
