Comment 2 for bug 879120

At some point, the open source firmware was no longer installed from the firmware-b43-*installer packages, which now download the Broadcom drivers and use b43-fwcutter to install the firmware. I'm not sure what happens when the Broadcom STA driver is used, since it contains the firmware within the driver, and does not require the installation of firmware in a directory. Bugs like 1061639 are indicating problems with bdus/network-manager delays in shutdown, so this sort of delay may be a contributing factor.
