Please send more information about the new server. Sometimes there are  
bugs found in drivers with large disks, etc. Or firmware of hardware.
The contents of /var/run/dmesg.boot is interesting to a lot of people.
As is the output of zpool status.

As you are having trouble with swap on zfs. Is it possible to put that on  
a separate disk for the test?
