Hi, I have the following config: 1. DG43GT motherboard with 4GB memory 2. br10i SAS adapter 3. 16x Toshiba SAS drives connected to expander backplane. I am able to create a zfs pool ok without any errors but as soon as I do a scrub on that pool I get tons of scsi errors. Here is my dmesg output: http://pastebin.com/81AUsG6q (da3:mpt0:0:12:0): READ(6). CDB: 8 0 b2 f1 6f 0 (da3:mpt0:0:12:0): CAM status: SCSI Status Error (da3:mpt0:0:12:0): SCSI status: Check Condition (da3:mpt0:0:12:0): SCSI sense: ABORTED COMMAND asc:4b,3 (ACK/NAK timeout) I have a similar setup with desktop SATA drives and I see no issues. I have tried replacing motherboard and SAS adapter but no luck. I have already tried following in my loader.conf hw.pci.enable_msix="0" hw.pci.enable_msi="0" Any help would be appreciated. Thanks.
