This bug has been reported previously for Redhat and Arch: https://bugzilla.redhat.com/show_bug.cgi?id=1250279 https://bugs.archlinux.org/task/45787?string=%5Blinux%5D The details of the trace are attached to those reports. My trace is pretty much identical. A patch has been released that is going to appear in kernel 4.2: http://www.spinics.net/lists/linux-input/msg40330.html Would it be possible to add it as Ubuntu patch?
