Title:
14e4:4365 bcmwl-kernel source: fix for null pointer crash
Status in bcmwl package in Ubuntu:
That's too bad. I'm one step from updating to vivid. One interesting
tidbit I found in dmesg output:
[ 11.564768] wlan0: Broadcom BCM4365 802.11 Hybrid Wireless Controller
6.30.223.248 (r487574)
Is BCM4365 an alias? Or what could be the reason for this?

Sergey, that is very much possible.
I'm now on vivid (via do-release-upgrade -d), The problem reappears

Christopher M. Penalver, the output is:

I need advice on whether I should be opening a new bug, or is it OK to
stay with this one?
