I don't know what anybody did to resolve this issue... at least for me
it still exists.

mmc0: Unknown controller version (3). You may experience problems.
mmc0: Hardware doesn't specify timeout clock frequency.


lspci shows following controller:
02:00.0 SD Host controller: O2 Micro, Inc. Device 8520 (rev 01)


I am running ubuntu 13.10 on a Thinkpad W540

Title:
  1217:7130 O2 Micro, Inc. Integrated MS/xD Controller (rev 01) Media
  Slot does not read cards

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I am running Ubuntu 11.04 Natty Narwhal on Fujitsu E8210 laptop. It
  has built in media slot / card reader which does not seem to be
  working with the latest release of ubuntu. It worked with previous
  older releases but I haven't used it for a while (the card reader) and
  am not sure when exactly (during which distro) it stopped working. I
  know for sure that it did not function in two previous releases.

  I am running Win7 in dual boot and the card reader is working fine in
  windows environment.
