Bug Description

== 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.


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.

I can confirm the bug. Exactly the same problem, except it a MacBookPro8,1 on kernel 3.2.0-17 64bit.

I have this issue with MacBookPro8,1 but the difference is that I only need to reload the b43 module and wireless starts working.

The fix just hit Linus's tree, and quantal will get it in the rebase to 3.5-rc3. Attaching backport for precise.

This bug is awaiting verification that the kernel for Precise in -proposed solves the problem (3.2.0-27.43). Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-precise' to 'verification-done-precise'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
