Recently got a silicon image 3124 card to upgrade my Sun Ultra 10 to let it support SATA drives effectively. Put the card in and gave a couple of tests. fscked a 1T filesystem with ~30 million files. No problems, mounted the filesystem and did a checksum of a subdirectory to hundreds of FS errors (looking for blocks well outside of the partition). Unmounted, redid fsck. fine. Redid fsck while doing a 'dd if=/dev/ada1 of=/dev/null' and the fsck instantly died with unexpected errors. Next I did a 'dd if=/dev/ada1 bs=126b count=8192 | sha256' got an answer, re-ran it and got the same answer. reran again while running another dd if=/dev/ada1 bs=126b of=/dev/null in a different terminal and received a different sha256 sum. Kept repeating it and getting different answers. Killed the background dd and received the first answer again. Tried with and without MSI; also tried to fall back and use the ata-siliconimage driver, that one fails to attach (I believe its failing on the LINEAR map, but very hard to tell given there isn't a specific error message in that part of the driver). I repeated this with 2 different cards in an U10 and a U5; these are stock machines, nothing else in them other than this card; I can get a boot verbose later, but this is really a vanilla config.
