Blackgr, thank you for reporting this and helping make Ubuntu better.

Could you please test the latest upstream kernel available from the very
top line at the top of the page from http://kernel.ubuntu.com/~kernel-
ppa/mainline/?C=N;O=D (the release names are irrelevant for testing, and
please do not test the daily folder)? Install instructions are available
at https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow
additional upstream developers to examine the issue.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, and Y are the first two numbers of the kernel version, and Z is
the release candidate number if it exists.

If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of
kernel-bug-exists-upstream.

Once testing of the latest upstream kernel is complete, please mark this
report's Status as Confirmed. Please let us know your results.

Thank you for your understanding.

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

Status in linux package in Ubuntu:
  Incomplete

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

  [ 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.
