description |
When the machine is suspended without external power attached, after being resumed the wireless is unable to associate. Analysis with wireshark shows that no frames are being transmitted by the laptop when this happens, although it is able to receive frames as it can successfully scan. The problem can be fixed by unloading both the b43 and bcma modules and reloading them; unloading and reloading b43 by itself is not enough to fix the issue.

== SRU Justification ==
Impact: Macbook Pro models with BCM4331 wireless will be unable to transmit wireless data following S3 if resumed without external power attached.
Fix: Add workaround to BCMA to reinitialize the ext_pa pin muxings after S3.
Test case: Suspend an affected machine, then resume it without A/C power. Observe that without this patch the wireless fails to work afterwards, whereas with the patch the wireless does work.
