(That was an older | version of the patch, though). FYI, Saulius ported the Intel RAID meta data to 5.3 a while ago. I put it up at: http://www.ambrisko.com/doug/ata/5.3-intel-raid-meta-data.patch FYI2, I should have a newer version of my ata patches since I finally figured out a bug I was having with a NFS root mount. The nfs_syncer spin-loops on bp queues and expects an interrupt routine to break it out on the side. Then soft updates tends to re-schedule work even when there is no work to do. These aren't really part of the ata stuff but are required to make it work better. Lastly I've made some more RAID robustness changes to deal with some error conditions we've caused here in testing. I need to roll them out of our dev. tree into my release tree. Then I should finally start getting to merge the HW support into FreeBSD 4.X tree now that I know the spin-loop bugs I was seeing wasn't something wacky in my code. Doug A.
