This has been happening to me off and on since the upgrade to 3.16.0-71-generic (64-bit). 70-generic would just randomly panic, so until 71 came out I was running 69-generic. 71-generic seems to panic sometimes when I plug in my Android phone, or when I dismount it -- but it hasn't shown problems with my Cannon PowerShot S3IS (cameras are the only "removable media" I've been using lately).
You may just want to run 69-generic. Have you sent in a bug report? (Have I sent in a bug report? No, but I think I should!)
