Can you paste the exact error? Are you getting something like:
error 1: lba 32
error 1: lba 1
When I've seen the above sequence, it was due to a stack overflow (IIRC),
with the result that the loader would start a second time and barf out these
errors.
The "large number" in the error might give us a clue as to what's going on.
If the number is really large, it might be an indication that your BIOS
doesn't reliably read past a certain threshold. ZFS writes a sort of label
at the beginning and end of its drives; perhaps the loader is trying to read
the label at the end of the disk and is failing (I don't recall whether it
tries to read both labels).
