StefanF (stefan) , as i see ubuntu not very interesting to solve this
bug. Nothing changed in past six months.

I think best off all - write to lkml or stable@xxxxxxxxxxxxxxx and ask
help from kernel devs.

P.S. I have this problem and want to say very big thanks for your

  14e4:16bc  [Acer Aspire One 756] SD card slot doesn't work

Status in The Linux Kernel:
Status in “linux” package in Ubuntu:

Bug description:
  My SD Card reader will not work without reloading the tg3 module. When I insert an SD card, dmesg output:
  [ 409.712345] mmc0: Timeout waiting for hardware interrupt.
  [ 419.722227] mmc0: Timeout waiting for hardware interrupt.
  [ 429.732104] mmc0: Timeout waiting for hardware interrupt.
  [ 439.742025] mmc0: Timeout waiting for hardware interrupt.
  [ 443.841471] mmc0: Card removed during transfer!
  [ 443.841477] mmc0: Resetting controller.

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

  With Ubuntu 11.10, which works fine out of the box. Dmesg does not
  show any error or warning.

  10.04: Does not work even when reloading the tg3 module. Dmesg reports error -84 during SD card init.
  12.04 32-bit: Works when reloading the tg3 module. Otherwise timeout errors occur.
  13.04 32-bit: same as above with 12.04.
  12.04 with 3.10.0-rc1 mainline kernel: same as with 12.04.

  WORKAROUND: setpci -s 00:1c.2 0x50.B=0x40

  WORKAROUND: setpci -s 00:1c.2 0x50.B=0x41
