But much more important, there's a patch included which tells atacontrol=20 how to spin disks down. I guess this was for ATAng. Is there any reason not to include that into ATAmkIII? Now that we have such a nice cpufreq meta driver in RELENG_6 I'd really=20 love to see the hungry HD spin down, ideally managed by powerd ;) But even if the "delayed write" feature is problematic, the ataidle feature= =20 really should make it into ATAmkIII before 6-RELEASE IMHO...
