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: insert card: [ 409.712345] mmc0: Timeout waiting for hardware interrupt.
