Hi Po-Hsu,

According to your above log, we can use below method instead to dump
only the pci device we need to check only.

 a. Use Kernel 3.13.0-031300 and Cold boot to Linux, 
     sudo su 
    lspci -vxxxx -s 01:00.0 > o2dev_log1
    lspci -vxxxx -s 00:1c.0 > rcdev_log1

b.Use Kernel 3.16 or newer and Cold boot to Linux
     sudo su 
    lspci -vxxxx -s 01:00.0 > o2dev_log2
    lspci -vxxxx -s 00:1c.0 > rcdev_log2

 c. Then Reboot the OS, this time the card reader will disappear. 
     sudo su 
    lspci -vxxxx -s 00:1c.0 > rcdev_log3

Step C  only get 1 log as our device is not exist.
If you find freeze case when get rcdev_logx. please use lspc -vxxxx | more to get instead, and contuine to get all log files.

Thank you very much.

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.
