aswin venugopal, the next step is to fully commit bisect from kernel 3.13 to 4.4 in order to identify the last good kernel commit, followed immediately by the first bad one. This will allow for a more expedited analysis of the root cause of your issue. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ?
Please note, finding adjacent kernel versions is not fully commit bisecting. Also, the kernel release names are irrelevant for the purposes of bisecting. It is most helpful that after the fix commit (not kernel version) has been identified, you then mark this report Status Confirmed. Thank you for your help. -- 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/1619592 Title: Lenovo g50-30 Elantech Touchpad stops working after some time in ubuntu 16.04 Status in linux package in Ubuntu: Incomplete Bug description: The elantech touchpad works on booting into the system but stops working after sometime.
