Title:
  SD card reader on Dell E7450 doesn't work in Ubuntu 15.10

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Under ubuntu 15.10 I can't use my Sandisk ultra 64GB microSD (with a
  SD card adapter) with the built in SD card reader. I seem to be
  getting the following errors.

  [ 1268.126602] sdhci: Timeout waiting for Buffer Read Ready interrupt during tuning procedure, falling back to fixed sampling clock
  [ 1268.128381] mmc0: tuning execution failed
  [ 1268.128386] mmc0: error -5 whilst initialising SD card

  [ 1268.993995] sdhci: Timeout waiting for Buffer Read Ready interrupt during tuning procedure, falling back to fixed sampling clock
  [ 1268.995778] mmc0: tuning execution failed
  [ 1268.995786] mmc0: error -5 whilst initialising SD card

  [ 1269.455449] mmc0: tuning execution failed
  [ 1269.455458] mmc0: error -5 whilst initialising SD card

  It was working fine under vivid with kernel 3.19.

  Went through all the kernels from 3.19 to 4.2
  (http://kernel.ubuntu.com/~kernel-ppa/) and found out that until
  4.1.8-040108-generic the SD card reader would play fine and only after
  I put 4.1.9 and on I started getting the errors.
