ZFS: zpool import panic - assert on zap_lookup ddt.c

[ivdreg ivdreg]

Hi all,

I wrote about my problem in forum but there are no suggestions. I think in
forum link there is enough information about the problems and I will not
re-post all the data. There you can see in my second post why I write to
the list.

Can someone give me idea how to continue on troubleshoot and fix this issue
?

Regards
