Comment (by obo):

 Just quick note, details will follow. Any hints of which additional logs
 to check is welcome.

 I have the same problem on Lenovo S10e - and my wifi is also using bwn

 Steps to reproduce are very easy: open the UI and click Apply after ANY
 change (even not changing any wifi related things will cause the issue).
 This will immediately freeze the OS completely (hard reset needed) and
 after reboot, rc.conf is empty. It does not affect wpa_supplicant.conf (so
 in my case, non-empty wpa_supplicant.conf is not corrupted).

 Fresh installed rc.conf contains both bwi and bwn (and accompanying
 siba_bwn and firmwares v3, v4), leaving only bwn (and siba_bwn and
 bwn_v4_ucode) does not solve the issue.

 What I also found is that UI is not reading existing wpa_supplicant.conf
 (I have manually configured wpa_supplicant and rc.conf to have wifi
 working) - so my running wifi configuration is not visible in the UI.

 /var/log/messages does not show anything abnormal.

 Current behavior also exposes a problem where UI is modifying a file but,
 in fact, I have not found any backup copy of it anywhere.

 I will send obvious logs (messages, ifconfig, wpa_supplicant, etc.) later.
 Is there any specific log which can provide more details of what the
 network UI is doing?
