As recommended in FreeBSD forums I'm posting the message here.

I have a peculiar case where NAS4Free has corrupted the meta-data on my =
4-disk raidz pool and a few flavours of FreeBSD and a latest version of =
OpenIndiana I've tried go down just when I try zpool import with no =
additional parameters (kernel panics).

I have more or less given up of my precious data, but if any FreeBSD dev =
wants to investigate or help me fix the problem I'd gladly try any =
special build you'd want me to.

PS. I've tried removing disks one by one, but any 3 out of 4 cause =
kernel panics and with just two I can't get my data back.

PPS. zdb -l works and reports valid information about zpool =
configuration, but I can't fix any problems with zdb.
