Comment 44 for bug 604122

Hi had the same issue with Kernel 3.2.0-29-generic-pae and Muhali's workaround works.
When booting with the card inserted, it is sometimes recognised, sometimes you need to insert the SD card several times.

I am all new to ubuntu/linux as a laptop OS and if you have links on how to help to troubleshoot this kind of issues (enable debug logs etc...) I would be more than happy to contribute.
