** 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,
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.
Brad and Joseph: I have tried v3.13-rc7-trusty, thanks for the kind
reminding!
It seems that problems have been identified here are the post I found:
