[Bug 1346067] Re: [Dell Latitude E5440] O2 Card reader [1217:8520] could not be detected after rebooting this system

 

Hi Po-Hsu,

I am Vendor who is to check this issue.

Sorry for I don't tell you clearly in last talk. Before use lspci
command, We need to get root privilege first; otherwize the log will be
not contail enough information.

Below is the update steps:

    a. Use Kernel 3.13.0-031300 and Cold boot to Linux, Then "sudo su" to get root privilege and  "lspci -vxxxx > log1"
    b. Use Kernel 3.16 or newer and Cold boot to Linux, Then "sudo su" to get root privilege and  "lspci -vxxxx > log2".
    c. Then Reboot the OS, this time the card reader will disappear. Then "sudo su" to get root privilege and "lspci -vxxxx > log3".

I am really very sorry to trouble. Could you get the log again, thanks.

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.
