I have the same problem with Ubuntu 12.04, Kernel 3.2.0-39-generic-pae on an Acer Aspire One 756.

Steps to reproduce:

1) Insert an SD card
2) dmesg says repeatedly: mmc0: Timeout waiting for hardware interrupt
3) rmmod tg3 -> nothing happens with the SD card
4) modprobe tg3 -> Gnome provides to open the media in file manager, which works fine now.
5) rmmod tg3 ->Cardreader is still functional

The type of SD card does not matter and it does not matter if an ethernet cable is plugged.

dmesg output:
