For the first time in some while I booted up Ubuntu to try and provoke
this issue. I copied a memory card from my camera, but none of the
images were garbled. I have to say that this issue did not happen every
time and with every picture; it was usually fine, but every once in a
while the issue came up with some pictures. Therefore I am not surprised
that I couldn't see any corruption today. I guess the only way to get to
this bug is to continue using the card reader until I get the bug, and
then use that memory card as a test case for later.

But AFAIK the issue came up on cards where I had deleted bad pictures to
make room for more pictures. A newly formatted card that was just filled
up was not a problem, but a fragmented memory card seemed to be.
Therefore I suspect I can provoke the bug to pop up if I try to take
pictures, deleting them, taking some more, ... and then try to read the
card. I tried doing something similar to this today by copying and
deleting files to the card, and that actually crashed the FAT
filesystem! I don't know if that is related, but I am attaching that
kernel log anyway.

I will be back with more information (upstream kernel and 9.10 image)
when I am able to get some corrupted images again. Could take a while,
though ...

** Attachment added: "Kernel log from when deleting files & copying files to 
the memory card crashed the FAT file system."
