2 days later. It happened a few more times. New observations:
I can observe three different behaviors when the situation occurs:
* as noted above - I kill & start NetworkManager and everything's fine. Actually it only happened once.
* more frequent - the whole OS becomes unstable - I can use running programs, but can't run gnome-terminal. Even sudo doesn't work - I switched to CLI (via CTRL+ALT+F1). when I use sudo, it just goes to the new line and cursor blinks... and I can't do anything in that console.
* also happened a few times - I can kill & start NetworkManager and everything else seems to be fine, except it keeps connecting for ever. I ran sudo NetworkManager --no-daemon and saved the output (attached to this message).
Also, for the whole day today NM showed only one access point (it always shows 5-11 different APs).
