Comment 10 for bug 400652

This gets stranger and stranger. I wonder whether this is a special case for
one device (yours) or generic. It would be good to have someone with the same
phone either confirming or declining the effect.
The failing blocks when unplugging the phone somehow seem to include the last
sector, though I do not know what fdisk would do there. Would "fdisk /dev/sdc"
and then use 'p' to print the table work?
At this point this sounds a bit like something that might be interesting to
report upstream (though I struggle a bit to see how this could be fixed). But
for that it should be tested against a very recent kernel. Could you probably
pull a daily kernel from

http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/current/

You can install the kernel in parallel to your current and select which to boot
from grub.
