Apple Wireless Trackpad causes kernel (3.12.x/3.13.rcx/3.14.rc1) crash

[Baif]

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.

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)

A voluenteer tests the patched kernel (from http://koji.fedoraproject.org/koji/taskinfo?taskID=6430928) with patch (from http://www.spinics.net/lists/linux-bluetooth/msg41904.html). And it seems that kernel works with trackpad without crash.
