I have a problem trying to mount a SD card in Ubuntu 12.04. The message what I get from the system is:

mmc0: error -110 whilst initialising SD card

I'm on the 3.5.0-24-generic kernel.

I check previous kernel 3.5.0-15 and card is on the system. I think is some bug in kernel.

I was looking some solution on web. They say my card is dead (but is working)

What I should do?

Some more information on this issue here. If someone have more question about my hardware just ask.

Can you please indicate your laptop's make and model? also if you could run lspci -nn and lsusb and add the output to your post it would be useful. This helps determine which card reader you may have and whether there is a known problem with that model. –  roadmr Apr 3 '13 at 20:25
    
I had a similar problem with a Sony laptop, quite a while ago. It would occasionally go to a state where it would give the exact same error to all SD cards. As a workaround I think reboot helped, but it was eventually fixed by a kernel upgrade. Would it be possible to try, say, Ubuntu 13.10 from a USB stick and see if this has been fixed? 13.10 has kernel 3.11.0. –  taneli Oct 29 '13 at 7:29
    
If the problem presents itself with a specific kernel and with the previous not, then is a bug. –  Braiam Dec 15 '13 at 19:31

What does mount -t vfat /dev/mmcblk0 /tmp show? and any messages in dmesg? Error sounds like a bad formatting. Try the bottom comment: forums.opensuse.org/english/get-technical-help-here/hardware/… (testdisk to check the disc) –  Rinzwind Dec 15 '13 at 19:38

Bug fixed bugs.launchpad.net/ubuntu/+source/linux/+bug/1158982 just upgrade your kernel –  Braiam Mar 30 at 16:15

Basically this error arises only when the SDcard got damaged. But as you mentioned its working, Please try the following steps and share your feedback.

  • Please check the output of dmesg / lsusb to check whether it detects the SD card.
  • Open the "Disk Utility" application and check whether your SD card is listed. If its listed, just click it -> Unmount Volume -> Format the Volume with suitable filesystem.
  • Also, try mounting the SD card on Windows and check whether it is working or not.

Also, you can downgrade your kernel by installing the old kernel / latest stable kernel version.

sudo apt-get update && sudo apt-get dist-upgrade && sudo apt-get autoremove

wget the latest stable kernal from Kernal Website

sudo dpkg -i *.deb

sudo update-grub2

Please select the proper kernal while booting and check whether your SD card mounts well!!
