I hit this one again, but this time my world and kernel are compiled 
with stock gcc. Pictures 3 to 5:

This happens on mounting root after unclean shutdown. I fixed my pool 
with booting amd64 kernel, after this i386 kernel starts fine.

Maybe it's just time to accept that ZFS on i386 is not stable? Current 
handbook elaborates on ZFS like it's known to work on i386.
