 I experienced the same problem. I setup a ZFS pool using the mpt(4) 
 drivers on a LSI SAS3041X-R with no problems, but then experienced some 
 weird issues with lockups (PR-117688) and attempted to switch over to a 
 native SATA setup using a Promise TX2plus SATA150 PCI card. I booted up 
 the server with the TX2plus and imported the ZFS pool, and as soon as I 
 tried moving some files there were immediately around 100 checksum 
 errors in ZFS and after more testing I easily created 2k worth of 
 checksum errors and over 100 unrecoverable errors using dd to write to 
 the disk. I was forced to destroy the pool because neither zpool or zfs 
 would function properly, and then switched back to the LSI controller.
