Comment 28 for bug 730215

Broadcom released a new version of firmware a couple days ago that fixes some crashes with these chips, see:

The patches haven't been merged into the linux-firmware repo yet, and I'm not sure what Ubuntu's process is for pulling
in new firmware, but hopefully it'll help with the stability issues.
