I've had a look into the more recent version of if_iwi.c in
CVS and applied only this change to the original 6.2R version
of if_iwi.c (1.8.2.10 2006/10/29) which was made by Luigi in
the version 1.8.2.13:


*** if_iwi.c	Wed May 23 07:45:32 2007
--- if_iwi.c.orig	Sun Oct 29 09:29:31 2006
***************
*** 2059,2073 ****
  
  	IWI_LOCK(sc);
  
- 	/*
- 	 * wait until pending iwi_cmd() are completed, to avoid races
- 	 * that could cause problems.   
- 	 */
- 	while (sc->flags & IWI_FLAG_BUSY) {
- 		printf("%s: waiting until pending iwi_cmd() are completed\n", __func__);
- 		msleep(sc, &sc->sc_mtx, 0, "iwiioctl", hz);
- 	}
- 
  	switch (cmd) {
  	case SIOCSIFFLAGS:
  		if (ifp->if_flags & IFF_UP) {
--- 2059,2064 ----

and during every reboot, exactly where the systems got frozen before, it
now printf 10 times the above message 'waiting until pending iwi_cmd'
but all is fine now;

Maybe you could try it as well or someone of the if_iwi.c
commiters could comment on it; or even it is worth to file a
bug report and close it with this patch so that people in trouble
have a chance to see it; thx
