Andriy,

I am not sure if this is the same issue, but
I have a similar problem running FreeBSD 9-CURRENT amd64 (sources as
of 1 hour ago)
a zfs lockup appears very frequently, it is a NFS server it locks up
several times per day.

I have been having these issues since before the ZFSv15 patch was
committed to HEAD a few months ago.
let me know if you need details, I have no problems giving you root
ssh on this machine... but it does  not have a serial port.
so I am not sure how useful it would be.
