[Bug 1415880] Re: bcmwl-kernel source: fix for null pointer crash
I have been running 6.30.223.248+bdcom-0ubuntu1 on trusty 14.04.1 LTS for several weeks. I applied the patch suggested by Andre yesterday, and haven't seen any kernel crashes yet. However, I am still seeing occasional (once per hour approx) loss of connectivity. A typical syslog extract is below: Feb 2 23:47:12 bacchus wpa_supplicant[1287]: message repeated 25 times: [ wlan0: CTRL-EVENT-SCAN-STARTED ] Feb 2 23:48:50 bacchus wpa_supplicant[1287]: wlan0: WPA: Group rekeying completed with 00:12:0e:54:e9:a4 [GTK=CCMP] Feb 2 23:49:12 bacchus wpa_supplicant[1287]: wlan0: CTRL-EVENT-SCAN-STARTED Feb 3 00:03:12 bacchus kernel: [ 3848.216125] ERROR @wl_notify_scan_status : wlan0 Scan_results error (-22) Feb 3 00:07:12 bacchus kernel: [ 4088.258526] ERROR @wl_notify_scan_status : wlan0 Scan_results error (-22) I have just checked the syslog and the error was also being logged prior to applying the patch. I wonder whether this error is relevant to this bug - sorry if it isn't. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1415880 Title: bcmwl-kernel source: fix for null pointer crash To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1415880/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1415880] Re: bcmwl-kernel source: fix for null pointer crash
Christopher Penalver, I'm not sure, I'm still on Utopic, but I'm currently downloading the alpha2 ISO; I'm going to inform you once I have tested. Also I have to report that the 'fix' is apparently not fully effective; yesterday the problem reappeared. Regarding the outdated BIOS; I could perhaps borrow a Windows 7 to update the BIOS (alas, Lenovo does not ship the IdeaPad BIOS update in a format that can be managed with Linux tools). Or would you like me to continue testing with the original BIOS? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1415880 Title: bcmwl-kernel source: fix for null pointer crash To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1415880/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The attachment Patch to fix the null pointer crash that happens with BCM43142 (and possibly other) chipsets seems to be a patch. If it isn't, please remove the patch flag from the attachment, remove the patch tag, and if you are a member of the ~ubuntu-reviewers, unsubscribe the team.

** Description changed: 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. Adding the patch is a fairly simple process: * put the patch file in /usr/src/bcmwl-6.30.223.248+bdcom/patches * add the following line to /usr/src/bcmwl-6.30.223.248+bdcom/dkms.conf PATCH[7]=0014-null-pointer-crash.patch * run: /usr/lib/dkms/common.postinst bcmwl 6.30.223.248+bdcom /usr/share/bcmwl x86_64 $(uname -r) - This has fixed the issue for me. + This has fixed the issue for me. Edit: I just wanted to add that I did + not write the patch; I merely downloaded it from a paste that was linked + from the respective AUR package.
