So, I've started with the tiring process of "printf debugging". I =
have gotten out of
the loader code, and can show that it's inside of the call to the zfs =
devsw dv_init()
call where it's failing.

Looking at dp 0x236970 (block), dv_init of 0x11f320
Calling dv_init()
Back from dv_init()

Next, I guess I'll have to find out where the code for that is, and =
work there.
If anyone has any ideas or can assist, please let me know.
