Bug Description
The SD card reader on this system doesn't work at all: no errors, no messages, nothing on SD card insertion. It's like it's not even there.
I think it shares the card reader with the systems reported on bug 773524, but the symptoms reported there were different.
This was reported working on Natty, so I'll try to install Natty and validate that it does. I'll report back once I know for sure.

Thanks for checking if this works in Natty. This could also be a duplicate of bug 880229
Also, would it be possible for you to test the latest upstream kernel? It will allow additional upstream developers to examine the issue. Refer to https:/ /wiki.ubuntu. com/KernelMainl ineBuilds . If possible, please test the latest release candidate kernel (Not a kernel in the daily directory). Once you've tested the upstream kernel, please remove the 'needs- upstream- testing' tag(Only that one tag, please leave the others). This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs- upstream- testing' text.
If this bug is fixed by the mainline kernel, please add the following tag 'kernel- fixed-upstream- KERNEL- VERSION' . For example, if kernel version 3.1-rc9 fixed and issue, the tag would be: 'kernel- fixed-upstream- v3.1-rc9' .
If the mainline kernel does not fix this bug, please add the tag: 'kernel- bug-exists- upstream' .
Thanks in advance.
