[Bug 1346067] Re: [Dell Latitude E5440] O2 Card reader [1217:8520] is not stable on this system


Cold boot and reboot with 3.13.0-031300 kernel, the O2 Micro Inc. SD/MMC Card Reader could always be found in lspci output.
Do you need to dmesg output for cold boot and reboot?

Bug description:
  CID: 201307-14017 Dell Latitude E5440

  The O2 card reader, O2 Micro, Inc. SD/MMC Card Reader Controller [1217:8520] (rev 01)
  is not stable on this system, the card reader cannot be detected.
  It works normally after reboot, but will be gone if you reboot it one more time

  1. Install 14.04 + update (3.13.0-32), boot to desktop
  2. Run lspci -nn to see if the card reader is there
  3. Insert a SD card
  4. Reboot, go through step 2 and 3 again

  Expected result:
  * Card reader should be found in lspci output, SD card should be mounted automatically

  Actual result:
  * Nothing happened, the card was not detected at all
  * On step 4, the card reader works, if rebooted again, it will be gone.
