Title:
  nvidia-352 driver won't load

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  After the latest kernel update for wily, to 4.2.0-29, i can no longer
  load the nvidia-352 driver. After noticing it was not being loaded on
  boot, i used `modprobe nvidia` to try loading it manually, and got an
  error:

  > modprobe: ERROR: could not insert 'nvidia_352': Invalid argument

  I found the following in my kern.log file:

  I have also booted into kernel 4.2.0-28 and the driver was initially
  not found (i had been running 4.2.0-27 previously, installed -28, but
  not bothered to reboot until after the -29 update). I used `apt-get
  install --reinstall nvidia-352` and then the driver loaded with no
  problem. I tried the same after booting back into the -29 kernel, but
  still no luck.
