--- Comment #23 from Alan Somers <asomers@FreeBSD.org> ---
Are you using ZFS atop geli?  If so, it shouldn't be possible to have unmapped
I/O in geli.  To check you can do something like the following:

sudo dtrace -i 'fbt:geom_eli:g_eli_crypto_run:entry /args[1]->bio_flags &
BIO_UNMAPPED/ {stack();}'

if it prints anything at all, that means you're using unmapped I/O with geli.
