Did you loaded zfs.ko?

This is not correct unless it's the first time and you have never
imported the pool again.  Some recent changes to ZFS mounting code may
have relieved the requirement of keeping zpool.cache but I have not
tested it myself.

Regenerate the zpool.cache with:

zpool set cachefile=/mnt/boot/zfs/zpool.cache zdell

Then sync; sleep 5; sync; then reboot.
