data integrity verification using geli

[Robert Simmons]

Does data integrity verification work if I encrypt a partition using
geli(8)?  When I created a provider, I just happened to peek at the
dmesg and I noticed a large number of errors reported after creating
the eli device.  All are variations of the following:
GEOM_ELI: ad6p4.eli: 512 bytes corrupted at offset 3221224960
GEOM_ELI: ad6p4.eli: 8192 bytes corrupted at offset 65536

and so on.

I also found the following PR (kern/152647):

I have tried all the algorithms listed in geli(8), and all give
similar sets of errors.
