Public bug reported:
When inserting an SDHC card into the Ricoh e823 card reader on my
Thinkpad T420s, the card is not mounted and the block device is never
created. There is a similar bug #773524, but the workaround provided
there and the updated kernel version haven't solved my problem. I would
love to help get this solved and am willing and able to test various
solutions.
In dmesg, I see "mmc0: error -110 whilst initialising SD card" after
inserting the card.
