    On the unsure if you should connect anything front -- I have a kernel I built just after those changes were merged in, with omnios-bloody, and it's running quite well so far. Mine's got 4 disks on it that are part of a 6-disk raidz2 vdev and it's been storing, ahem, non-critical bit torrent data (it's all Linux ISOs, obviously). It's been reading and writing at a few MB/sec for most of the week since then without any problems.

    That said, none of the disks attached have had any problems as yet -- handling errors is usually where newly supported controllers explode worst. So ymmv, naturally.

    On a semi-related note, I'm also using the newly added support for the ASMedia ASM106x chips on a couple of machines (all with mSATA SSDs attached, serving as mirrored ZIL/l2arc on quite busy but non-critical hosts) and it's also fine, just not the fastest thing ever (as expected from the price). Most of the changes for both these chips have just been relaxing the ahci code's expectations about the level of standards-compliance of the things it talks to, and some minor modifications for the newer revisions of AHCI. They're probably about as safe as brand new things get.
