I get a reproducible panic using this patch on smartos.
Steps to reproduce:
zpool create -f test c1t0d0
zfs create -o encryption=aes-256-ccm -o keyformat=passphrase -o compression=off
test/ccm
dd if=/dev/zero of=/test/ccm/disk
wait untit it dumps, will need a few GB of data written
I can provide the dump if needed.
panic[cpu1]/thread=ffffff000fb16c40:
BAD TRAP: type=e (#pf Page fault) rp=ffffff000fb16970 addr=2e occurred in
module "zfs" due to a NULL pointer dereference
