** Description changed: Apple Trackpad indeed crashes kernel 3.12.0-031200-generic on SAUCY. But 3.11.0-12/3.11.0-14 seem to be good. I have tried TRUSTY alpha1, either 3.12.0-6/3.12.0-7, both of them crashes with trackpad. AND, I also test Apple MagicMouse, none of mentioned kernel crashes with it....... The following threads have resolution for SAUCY with 3.11 kernels, BUT no for SAUTY with 3.12 nor TRUSTY with 3.12 (Haven't tried 3.13-rcx) Apple Trackpad indeed crashes kernel 3.12.0-031200-generic on SAUCY (and TRUSTY with 3.12). But 3.11.0-12/3.11.0-14 seem to be good. I have tried TRUSTY alpha1, either 3.12.0-6/3.12.0-7, both of them crashes with trackpad. AND, I also test Apple MagicMouse, none of mentioned kernel crashes with either SAUCY nor TRUSTY.......

It seems that problems have been identified here are the post I found: Bug 1027465 - Apple bluetooth magic trackpad crashes system https://bugzilla.redhat.com/show_bug.cgi?id=1027465 =============================================================== Michele Baldessari 2013-12-01 06:42:58 EST Seems the chromium guys had a similar issue: http://code.google.com/p/chromium/issues/detail?id=242344 They papered over the issue with: http://www.spinics.net/lists/linux-bluetooth/msg15564.html =============================================================== Michele Baldessari 2014-01-07 06:27:56 EST Thanks. Initial work to fix this is here: http://www.spinics.net/lists/linux-bluetooth/msg41904.html It has not been included in any tree yet as the patch is still under discussion =============================================================== Clarke Wixon 2014-01-07 13:48:15 EST Michele, going back to your 2014-01-03 inquiry - my vague recollection adds to the apparent consensus that this bug started around 3.11.x (though I don't remember any issues with 3.9). I think I started seeing it around October on Fedora 19, but at the time I was too busy with other matters to do any troubleshooting, so I just substituted my USB keyboard and trackball. Bluetooth input on 3.11/3.12 has been ALL KINDS of troublesome for me. The Apple keyboard also has been problematic (bug 1039738). I'm hoping the cleanup here will help on that as well.(https://bugzilla.redhat.com/show_bug.cgi?id=1039738) =============================================================== + --- + ApportVersion: 2.12.7-0ubuntu3 + Architecture: amd64 + DistroRelease: Ubuntu 14.04 + InstallationDate: Installed on 2014-01-01 (36 days ago) + InstallationMedia: Kubuntu 14.04 LTS "Trusty Tahr" - Alpha amd64 (20131228) + Package: linux (not installed) + Tags: trusty + Uname: Linux 3.14.0-031400rc1-generic x86_64 + UnreportableReason: The running kernel is not an Ubuntu kernel + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: + + _MarkForUpload: True ** Attachment added: "ProcEnviron.txt" https://bugs.launchpad.net/bugs/1266153/+attachment/3971204/+files/ProcEnviron.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1266153 Title: Apple Wireless Trackpad causes kernel (3.12.x/3.13.rcx/3.14.rc1) crash To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1266153/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
