I commented out IEEE80211_FEXT_SWBMISS (line 1075) from if_bwn.c and
rebuilt the kernel and now the machine has been running for 2 hours without
any panics.  Without this patch it usually panics within a few minutes or even
seconds after I boot and log in.

However, something weird is definitely going on.  I've seen these messages
about "RF switch changed to ON/OFF" before but I just ignored them.  Now they
seem to have become more frequent and the wireless actually stops working
now and then when it switches to OFF, but not always...
