I had this issue with previous kernels, but I don't know when the
problem
started. I once was able to read this card.

Not sure what filesystems are on either card, not sure if it matters.
The cards are not mounted automatically so I am guessing that the
file system doesn't become an issue until mount time.

The device is a Phison 6-in-1 and has no problems with
other cards.

When inserted this card causes no problems:

This is a 128MB card:

Looks like your kernel is configured to use the ub "low performance USB storage" driver, you could try the normal USB storage driver instead..



When the next card is inserted the keyboard partially locks up, the
special laptop keys work still.
e.g. the fn-contrast up/dn works still but not other keys work

Removing the card returns things to as before insertion.

This is a 64MB card from a phone:
