This is an issue I've been having with several distributions, but I've decided to use 13.10, at least until 14.04LTS comes out.

I'm using a Dell Mini 9 (Inspiron 910) which has a JMicron JMB385 card reader built in. When I suspend my session (e.g. by closing the lid), and resume, any SD card that was present disappears, and cannot be remounted unless the system is rebooted. All other installed hardware works fine to the best of my knowledge.

The card reader worked fine with Xubuntu 12.04LTS, but I'd rather not reinstall again.

Is there a patch or setting that might work to fix this?
