The only proprietary driver running is bcmwl. Because of the fact that freezing happens immediately on changing Network settings, I think that bcmwl is the cause. Symptoms: System freezes completely, screen does not turn off. Occasions: A) If NetworkManager selected one Wifi to connect, and I click on a different one to connect, sometimes system freezes. B) After setting up wifi without IPv4 (set IPv4 on “ignore” in Network Manager) and connect it to IPv6, it first looks fine. “ping6 google.com” works like expected. When then starting Firefox or XChat IRC, System freezes. Notes: - I do have a native IPv6 Internet connection - I experienced no such problems with Ubuntu 14.10, so I guess it is related to kernel/bcmwl compatibility, since the driver version used to be the same. - there are no logs in /var/crash bcmwl version: 6.30.223.248+bdcom-0ubuntu2 kernel version: 3.19.0-25-generic ProblemType: Bug DistroRelease: Ubuntu 15.04 Package: bcmwl-kernel-source 6.30.223.248+bdcom-0ubuntu2 ProcVersionSignature: Ubuntu 3.19.0-25.26-generic 3.19.8-ckt2 Uname: Linux 3.19.0-25-generic x86_64 NonfreeKernelModules: wl ApportVersion: 2.17.2-0ubuntu1.2 Architecture: amd64 CurrentDesktop: Unity Date: Wed Aug 12 08:51:08 2015 EcryptfsInUse: Yes InstallationDate: Installed on 2014-11-15 (269 days ago) InstallationMedia: Ubuntu 14.10 "Utopic Unicorn" - Release amd64 (20141022.1) SourcePackage: bcmwl UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1483998/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
