[BCM4313] If bcmwl is installed, bcma and brcmsmac modules should be blacklisted

[James M. Leddy]

The upstream kernel module brcmsmac claim there is support for BCM4313. However, it isn't 100% yet (in Oneiric). If the bcmwl package is installed to support this device, the brcmsmac module should be blacklisted.

Steps:
1. get laptop with BCM4313 and load the latest image on it (20120516-1)
2. step out to parking lot and view wireless networks that are available with nm-applet
3. blacklist bcma and brcmsmac modules (add 'blacklist brcmsmac' and 'blacklist bcma' in separate lines with out quotes to /etc/modprobe.d/blacklist-brcmsmac.conf)
4. reboot laptop
5. step out to parking lot and view wireless networks that are available with nm-applet

Expected results:
number of available wireless networks are the same in step 2 and 5

Actual results:
more wireless networks are available in step 5

SRU request:

blacklisting "brcmsmac" and "bcma" is something that we already do in Precise and Quantal, so the changes are really more of a backport.

See my package in oneiric-proposed.

Hi alberto, are you saying that this bug is "Fixed Released" for all the affected series?

[Alberto Milone (albertomilone)]

Yes, except for oneiric
