Comment 5 for bug 773524

It appears that this SD card reader may be the same that is found on the Lenovo X220, which works (717435). I would leave room for someone with more expertise to verify the system here and on 717435 are actually the same SD card readers. Is there a way to verity that any firmware involved is the same or running different versions?

But we have two R850s, one Intel based, another AMD based, that both have this problem. So it is unlikely a dirty card reader.
