Weird. Actually, I would rather blame the partitioning code than
the usb-storage as such.

Want a practical suggestion? Try to stick the card into a common
many-in-one reader, a SanDisk SDDR-somenumber would usually work.
Save the data.

Well, duh.

BTW Andrew added:

Maybe in FAT... See the sector number (1987576).

BTW, all Fedora kernels have usbmon enabled. May I see the trace?
Best of all, take the one from the working 2.6.24 (if such install
is still available). It would become obvious if usb-storage began to
do something different.

Obligatory notice: I don't think ub would fix this.
