======
Update the issue debug status:

(1) We don't have Dell E5440 NoteBook at WH now; and we can't reproduce
this issue by our platform.

(2) We reviewed the our register setting; and don't find any issue.

(3) We suspect this issue may cause by BIOS and Platform feature setting conflicted with our sdhci-pci-o2micro setting.
    We are asking Dell for schematic for Our Card Reader Chip now.

By the way, do you have this notebook or not?
In order to do get more info, could you help us to get lspci log for following 3 log:
        a. Use Kernel 3.13.0-031300 and Cold boot to Linux, Then  "lspci -vxxxx > log1"
      b. Use Kernel 3.16 or newer and Cold boot to Linux, Then  "lspci -vxxxx > log2".
      c. Then Reboot the OS, this time the card reader will disappear. Then "lspci -vxxxx > log3".

Title:
  [Dell Latitude E5440] O2 Card reader [1217:8520] could not be detected
  after rebooting this system

Status in HWE Next Project:
  New
Status in “linux” package in Ubuntu:
  In Progress

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

  Steps:
  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.
