[Kernel-packages] [Bug 1415880] Re: 14e4:4365 bcmwl-kernel source: fix for null pointer crash
For a while I stopped using suspend and it seemed promising, but today I experienced problems directly after booting. 1) I'm afraid the log I posted earlier was not very meaningful. I triggered the behaviour by closing the lid of my laptop because this was a way to safely reproduce the issues. This seems to be a physical problem of my laptop. Probably the wifi antenna gets shielded when the lid is closed. In Windows 7 connection quality drops significantly and bandwidth goes down to 300 KB/s. In Linux the connection goes down completely (ping says Network is unreachable), produces the messages I posted earlier, including the call traces. As annyoing as this is, it is probably nothing we can do anything about. The driver might not work as efficient as in Windows but that's it. 2) This only means that broadcom WL driver tried to warn kernel that it roamed from one AP to another and new BSS could not be found (meaning that the card could not get all its new BSS - peers, APs, etc). My network consists only of one BSS (router), but I tried it anyway. I set the mac address of my router in the BSSID field in the networkmanager interface. This didn't change anything at all, I still got call traces, indicating, according to you, failed roaming attempts. 3) I attached the syslog from this morning. The problems start at 11:40:16 with 2 call traces. At 11:40:57 wpa_supplicant gives CTRL-EVENT-ASSOC-REJECT messages. Google recommends blacklisting certain modules, but none of them are loaded on my system. Another call trace follows and networkmanager says it's disconnected. It goes on a bit and finally re-establishes the connection. This seems to be more or less stable for already two hours or so. I really don't know what to make of this. I can't see a distinct pattern. I'm not dependent on Wifi, so it's not a big deal. Yet I'm still interested in solving this issue. My next step would be to test the whole thing without networkmanager and see how things are then because I think networkmanager really complicates debugging this. I wanted to explicitely set wpa_supplicant to use WPA2-CCMP only because in some setups I experienced connection problems when this wasn't explicitely set, but networkmanager doesn't offer me a way to do this. ** Attachment added: "connection-loss.txt" https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1415880/+attachment/4459212/+files/connection-loss.txt -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to bcmwl in Ubuntu. https://bugs.launchpad.net/bugs/1415880 Title: 14e4:4365 bcmwl-kernel source: fix for null pointer crash Status in Dell Sputnik: Confirmed Status in bcmwl package in Ubuntu: In Progress Bug description: [Impact] * bcmwl does not compile on new kernels (or HWE kernels) * bcmwl suffers from null reference bug [Test Case] * public PPA provided to community and feedback * based on patch available to other distros * comment #42 [Regression Potential] * for changes on kernel support it may not compile (tested with 3.2, 3.13, 3.18 and 4.2) * for the null reference change -> proved to fix problem for community based on feedback [Other Info] Original bug description: The bcmwl package as of now misses one patch for a bug that occurs with BCM43142 and possibly other broadcom chipsets that will look like random disconnects, poor wifi signal and kernel warnings, See also #1379524.

[Kernel-packages] [Bug 1415880] Re: 14e4:4365 bcmwl-kernel source: fix for null pointer crash
@Rafael: thank you for your efforts to fix this issue. 1) I need more information than this. The PPA I provided works with Trusty, Vivid and Wily with 3.13, 3.18 and 4.2 kernels. - # TRUSTY (fix for future lts-wily kernel) Trusty needs a fix for 4.2 lts-wily future kernel: bcmwl, 6.30.223.248+bdcom, 3.13.0-63-generic, x86_64: installed # trusty bcmwl, 6.30.223.248+bdcom, 3.19.0-27-generic, x86_64: installed # vivid-lts bcmwl, 6.30.223.248+bdcom, 4.2.0-4-generic, x86_64: installed # wily-lts (fixed) - I'm confused - I have Linux martin04 3.19.0-26-generic. Is this ok or not? I aquired this kernel by following this: https://wiki.ubuntu.com/Kernel/LTSEnablementStack If my kernel is not supported I will try a different version. 2) I'm afraid I was not really aware of the suspend problem which means that my problems can also be linked to the suspend feature which I use heavily. For this reason I never tested how things work with a freshly rebooted system. I'm doing this test right now and will get back to you with the results. 3) I looked for a log and attached it. It starts with the device waking up from suspend mode at 12:30. Everything is fine for about 30 minutes. The problems start at 12:57:09. What is the right term for the crash that is happening? It certainly is no kernel panic and the system does not crash or freeze. But afterwards I have very long ping times (1000 ms) and sometimes connection loss. Sometimes it seemed to get better after disabling/enabling the wifi adapter but I couldn't yet determine any particular pattern.

I had the same issues like #15, the path here didn't help. I'm still working on trusty. Because the old version worked flawlessly, I downloaded the package 6.30.223.141+bdcom-0ubuntu2 from http://www.ubuntuupdates.org/package/core/trusty/restricted/base/bcmwl- kernel-source and used dpkg to downgrade to this older version. Then I used sudo apt-mark hold bcmwl-kernel-source to prevent any problems in the future. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to bcmwl in Ubuntu. https://bugs.launchpad.net/bugs/1415880 Title: 14e4:4365 bcmwl-kernel source: fix for null pointer crash Status in bcmwl package in Ubuntu: Incomplete Bug description: The bcmwl package as of now misses one patch for a bug that occurs with BCM43142 and possibly other broadcom chipsets that will look like random disconnects, poor wifi signal and kernel warnings, See also #1379524.
