From mboxrd@z Thu Jan 1 00:00:00 1970 From: Nico -telmich- Schottelius Subject: b43: BCM 4331: MacBook 8,1: No connection after suspend Date: Fri, 18 Nov 2011 18:32:42 +0100 Message-ID: <20111118173242.GA2101@schottelius.org> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii To: LKML , netdev@vger.kernel.org, Arend van Spriel Return-path: Content-Disposition: inline Sender: linux-kernel-owner@vger.kernel.org List-Id: netdev.vger.kernel.org Hello, new notebook, new problems (*): Running 3.2.0-rc1 on the MacBook Pro 8,1 with the BCM4331 (14e4:4331) the WLAN indeed works: [ 86.231702] b43-phy0: Broadcom 4331 WLAN found (core revision 29) [ 86.269190] ieee80211 phy0: Selected rate control algorithm 'minstrel_ht' [ 86.270486] Broadcom 43xx driver loaded [ Features: PMNLS ] [ 87.677265] b43-phy0: Loading firmware version 666.2 (2011-02-23 01:15:07) But: After a suspend it seems not to receive any packets anymore: [ 2334.494845] wlan0: authenticate with 64:87:d7:37:89:89 (try 1) [ 2334.694035] wlan0: authenticate with 64:87:d7:37:89:89 (try 2) [ 2334.893909] wlan0: authenticate with 64:87:d7:37:89:89 (try 3) [ 2335.093824] wlan0: authentication with 64:87:d7:37:89:89 timed out wpa_supplicant thus retries to connect to the network again and again without success. This is reproducable on the MBP 8,1 and is *NOT* fixed if I unload b43 and modprobe it again. It is also "not fixed" when doing multiple suspends/resumes. Any pointers to this? Cheers, Nico (*) feels like in good old times... -- PGP key: 7ED9 F7D3 6B10 81D7 0EC5 5C09 D7DC C8E4 3187 7DF0
