I'm not sure, but It's possible that I've had ATA subsystem but not
libata ... I haven't tested this case yet.
PS. I can see photos on my camera ... flash card is Ok. I have this
problem even if I changed the flash card in this camera.
It's more likely a usb-storage or scsi layer problem.
The device reports as having 1984001 sectors and the kernel is reporting IO
errors around the very end of the device. Presumably an IO is straddling
end-of-device and we're not handling that correctly.
Now I remember. We recently had a report about a buggy device, that close
to the end of the medium could handle only requests for single sectors.
I'll look into the archive.
Most likely this device just needs an unusual_devs entry with
US_FL_FIX_CAPACITY. I could prepare a patch to add this if you send
the output from "lsusb -v" for the camera or its entry in
/proc/bus/usb/devices.
