Created attachment 72908 [details] screenshot showing behaviour Reported as a bug in Launchpad Bug #875927 HP (6700 Series) Laptop with built-in SD (and multi-) card reader. SD card reader displays incomplete or corrupted files. Eg, jpgs shown as random coloured thumbnail or random characters. Some files are not displayed at all. Some files are correctly displayed. Also 'Error interpreting JPEG file (Bogus DQT index 15)' and 'Error interpreting JPEG file (JPEG datastream contains no image)' Lots of additional 'files' are displayed (as random symbols) which don't actually exist. Opening an affected file (if you can see it) does not work. Different error messages occur - 'could not open file' or 'type not supported' 'could not display' etc. Some correctly displayed files also yield these messages. The bug has been present since 10.10 (2.6.35) with no change through the subsequent versions. I have tested 12.04 as well as the mainline kernel 3.4.0-030400rc1 http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-rc1-precise/ I an unable to do a kernel bisect/commit, sorry. There's quite a lot of info (screenshots, apport-collect, dmesg) in the launchpad report + an earlier report Bug #649912 - please let me know what else would be useful and I'll do my best to attach/simulate/execute it.

hello.. anybody..?
kernel bugzilla is just used to track bug existence for the most part not for getting stuff fixed necessarily. If you want stuff fixed that's something to talk to your distribution about Moved to MMC/SD
The bug has been listed under various Bug #'s for over 2 years in Ubuntu Launchpad. Eventually it was deemed a 'kernel problem' and I was asked to submit an upstream kernel bug report, hence the reporting here.
The bug persists in mainline kernel v3.9-rc7-raring..
Please try this bug with latest kernel image.
