this fix mentioned in the previous comment is still necessary on every
reboot to make the SD card reader work in my Thinkpad T420s, even though
bug 773524 has been marked fixed ages ago.

It would be nice if us Lenovo users were not left behind Toshiba Tecra
users...

Title:
  SDHC card fails to initialize with error -110

Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  I am running an up to date oneiric install on a Lenovo X220i.

  When I put my Lexar 4GB SDHC card in the reader dmesg shows:

  [45040.698830] mmc0: error -110 whilst initialising SD card

  After a few seconds then hundreds of the folloing I/O errors:

  [45050.981675] end_request: I/O error, dev mmcblk0, sector 131
  [45050.981759] mmcblk0: error -110 sending status command
  [45050.981762] mmcblk0: error -110 sending read/write command, response 0x0, card status 0x0
  [45050.981765] end_request: I/O error, dev mmcblk0, sector 132
  [45050.981849] mmcblk0: error -110 sending status command
  [45050.981852] mmcblk0: error -110 sending read/write command, response 0x0, card status 0x0
  [45050.981855] end_request: I/O error, dev mmcblk0, sector 133 

  The SD card works fine in another system running Natty. This has lasted through several oneiric kernel updates.
