What do these changes bring BTW? Sorry, been out-of-touch these days :( > No ETA for the CAM changes. I need to talk with Alexander Motin about it, and I haven't gotten around to that. Too busy with other things. The changes just allow the driver to get notification from CAM about read capacity data instead of having the driver probe by itself. The probe in the driver for stable is kludgy, but does work. So it is perfectly fine to run the driver in stable/9 or stable/8 without the CAM changes. The latest mps(4) driver changes have been merged into stable/9 and stable/8, so this would be a good time to try it out. Ken -- Kenneth Merry ken@FreeBSD.org
