|  Jim Bednar, spooky things like booting from Windows intermittently allow
|  somethings to work is uncommon, but not unheard of. It's more towards a
|  timing or firmware issue that linux is not dealing with properly, that
|  obviously Windows has proper support for. 

Sorry if I was unclear -- booting into Windows didn't cause Linux to
work; it simply works fine in Windows, and only worked one time in
Linux (for no reason I know of, but not on the same day as testing
Windows), and otherwise has never worked in Linux.  

|  Would you be able to boot into
|  http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.17-rc2-utopic/ for
|  a mainline test?

I tried grabbing those .deb files (*all*.deb and *i386*.deb) and
installing them into my live USB system (the one you asked me to set
up last week).  However, that system now no longer boots, probably
just because of issues with it not quite being a real filesystem when
installing the kernel .debs.  I'm reluctant to try installing them on
my real OS setup, out of fear of making it unbootable too, but if you
think it's safe to do that I can try it.

Jim

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?
