|  |  |  Jim Bednar, could you please test the latest upstream kernel
|  |  |  available from the first line at the top page (not the daily
|  |  |  folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It
|  |  |  will allow additional upstream developers to examine the
|  |  |  issue. Once you've tested the upstream kernel, please comment on
|  |  |  which kernel version specifically you tested. If this bug is fixed
|  |  |  in the mainline kernel, please add the following tags:
|  |  |  kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER
|  |  
|  |  I tried, but failed to get the latest kernel to work.  The output from
|  |  my attempt is below, showing an error when installing, and when
|  |  rebooting into kernel-3.15 the system halted with "Kernel panic -- not
|  |  syncing: No init found."  I've rebooted into the slightly older kernel
|  |  (3.13), which works as it did before, but I don't know how I can test
|  |  3.15 right now.
|  
|  Actually, that's very strange -- I just tried the SD card reader
|  again, on a lark, and the SD card is now mounted and readable!  Yet
|  this is the same kernel version as I had originally, and lspci still
|  not apparently doesn't recognize the card reader:
|  
|  $ mount | \grep mmc
|  /dev/mmcblk0p1 on /media/jbednar/CANON_DC type vfat (rw,nosuid,nodev,uid=1000,gid=1000,shortname=mixed,dmask=0077,utf8=1,showexec,flush,uhelper=udisks2)
|  $ lspci | \grep Realtek
|  02:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. RTS5227 PCI Express Card Reader (rev 01)
|  $ uname -a
|  Linux novo 3.13.0-29-generic #53-Ubuntu SMP Wed Jun 4 21:00:20 UTC
|  2014 x86_64 x86_64 x86_64 GNU/Linux
|  
|  I have no explanation.

It only worked very briefly, and now it's back to pretending there has
been no card inserted.  It's a new machine, and seems unlikely that
the reader is worn out, but perhaps there is a loose connection?

Title:
  [Lenovo ThinkPad X240] RTS5227 card reader not recognized on running
  Ubuntu 14.04

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  According to
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1153618, support
  for the RTS5227 SD card reader was added in  2013 for kernel version
  3.5.0.  However, SD cards are not recognized for my Lenovo Thinkpad
  X240 running the much later release Ubuntu 14.04 with kernel version
  3.13.0, for which lspci reports:

  02:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd.
  RTS5227 PCI Express Card Reader (rev 01)

  That appears to be the same symptom as when there was no support at
  all.  Any idea what happened to the support for this SD card reader,
  or what I can do to work around it?
