Ok, this is a strange problem! You seem to have tried & eliminated all the possible issues that the community has suggested!
I was hoping you would see some errors logged in '/var/adm/messages' that would give a clue. Your original 'zpool status' said 140 errors. Over what time period are these occurring? I'm wondering if the errors are occurring at a constant steady rate or if there are bursts of error? Maybe you could monitor zpool status while generating activity with "dd" or similar. You could use "zpool iostat <interval>" to monitor bandwidth and see if it is reasonably steady or erratic. >From your "prtconf -D" we see the 3114 card is using the "ata" driver, as expected. I believe the driver can talk to the disk drive in either PIO or DMA mode, so you could try changing that in the "ata.conf" file. See here for details: http://docs.sun.com/app/docs/doc/819-2254/ata-7d?a=view I've just had a quick look at the source code for the ata driver, and there does seem to be specific support for the Silicon Image chips in the drivers: http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/uts/intel/io/dktp/controller/ata/sil3xxx.c and http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/uts/intel/io/dktp/controller/ata/sil3xxx.h The file "sil3xxx.h" does mention: "Errata Sil-AN-0109-B2 (Sil3114 Rev 0.3) To prevent erroneous ERR set for queued DMA transfers greater then 8k, FIS reception for FIS0cfg needs to be set to Accept FIS without Interlock" ..which I read as meaning there have being some 'issues' with this chip. And it sounds similar to the issue mention on the link that Tomasz supplied: http://home-tj.org/wiki/index.php/Sil_m15w If you decide to try a different SATA controller card, possible options are: 1. The si3124 driver, which supports SiI-3132 (PCI-E) and SiI-3124 (PCI-X) devices. 2. The AHCI driver, which supports the Intel ICH6 and latter devices, often found on motherboard. 4. The NV_SATA driver which supports Nvidia ck804/mcp55 devices.
