Title:
  Touchpad and mouse problem with kernel 3.13.0-83

Status in linux package in Ubuntu:
  Fix Released

Bug description:
  Hi,

  I'm using a laptop dell inspiron 15
  Intel® Core™ i3-4005U CPU @ 1.70GHz × 4 
  64 bits

  Description:	Ubuntu 14.04.4 LTS
  Release:	14.04

  When I start with the latest updated kernel 
  /boot/vmlinuz-3.13.0-83-generic
  I've no mouse. Even if I plug my usb mouse (usually I use the touchpad)

  I reboot with 3.13.0-79-generic and no problem.

  In the kern.log I found this (cat  kern.log | grep -i 'error') :
  kernel: [    0.000000] ACPI Error: Gpe0Block - 32-bit FADT register is too long (32 bytes, 256 bits) to convert  to GAS struct - 255 bits max, truncating (20131115/tbfadt-202)
  kernel: [   15.292896] usb 1-1.6: Direct firmware load failed with error -2
  kernel: [   17.896019] EXT4-fs (sda7): re-mounted. Opts: errors=remount-ro
  (I don't know if all these errors are helpful)

  I think this is linked to the kernel, because when I use a older one no problem, but perhaps I do a mistake.
  If you need more logs or stuff please ask me.

  Regards
  Romaric
