Under Solaris 10 u6 , No matter how I configured my ARECA 1261ML Raid card I got errors on all drives that result from SCSI timeout errors.

I'm positive that there is nothing wrong with my hardware. Here is the driver I used under Solaris 10 u6. ftp://ftp.areca.com.tw/RaidCards/AP_Drivers/Solaris/DRIVER/1.20.00.16-80731/readme.txt I got these errors using either JBOD or configuring the Drives as pass-through. I turned off NCQ and Tagged Queuing and still got errors. yoda:~/bin # zpool status pool: backup state: ONLINE status: One or more devices has experienced an unrecoverable error.
