While starting from Ubuntu 11.10 to 12.10 wl drivers worked like a charm on my broadcom 4312, it seems that the drivers in ubuntu 13.04 started causing kernel panics while using the network. The version I'm using is a fresh install of ubuntu 13.04 amd64 plus all the updates as of today and the home folder restored from an ubuntu 12.10 backup, but I don't think it could make the difference as the freeze happens also when logged as a "just created" user.
I'm pretty sure this problem is cause of broadcom drivers (or broadcom related network stuff) because as soon as I blacklisted wl, mac80211 and cfg80211 modules and plugged in an usb ralink wifi card it stopped to freeze.
