I'd like to suspend my ata disk. I dug up this old patch in freebsd-mobile and applied to 5.0-RELEASE-p4 and put hw.ata.suspend=1800 in my loader.conf I attach the patch. Two things: 1800 sec == 30 minutes. it suspends waaay before it's been 30 minutes. The same thing happens with 18000 also. I'd say it is at around 3 minutes or so. Second, it spins right back up almost right after it spins down. I noatime in all of my mounts. (/export in one disk, /nautilus in another, and a third disk spliced up into /usr, /var, /, etc) Even for /export and /nautilus which no process should be touching (and fstat doesn't show anything) the thing spins back up with in maybe seconds. I mean for the third mentioned disk, i'd suspect syslogd or some other thing, but since /export is spinning up as well, I didn't investigate. So does anyone know why it spins back up and why the timeout isn't working quite correctly? ===== --Seunghun Lee __________________________________________________ Do you Yahoo!? Yahoo!
