This seems to be related to Debian Bug#767204: request: backport i2c-hid suspend, resume fix from 3.17 to 3.16, which was fixed in Debian in linux 3.16.7-1 (https://lists.debian.org/debian- kernel/2014/10/msg00526.html).
I noticed the same bug in a friends notebook (Acer VN7-571G). Unfortunately i cannot test another kernel on this notebook now. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1401935 Title: [Acer Aspire V3-371] Touchpad stops working after suspend Status in linux package in Ubuntu: Incomplete Bug description: The touchpad stops working after suspend.
