Hi Peter,
This system is unable to dump all information from lspci -vxxx under root
privilege, seems that it will freeze silently in the middle of that command (in
both 3.13 and 3.16)
I tried to run "lspci -vxxxx | more" to see when it will freeze, it
truns out that this happened on dumping:

The next line will make this happen
(The attached lspci.2 output is created manually during the "lspci -vxxxx |
more" session)

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.
