You seem to have created a rather liberal imitation of the format used by send-pr(1) but this can not work.

Then the startup scripts will pick the changes and pass them to sysctl for you. > during boot up time the following message displayed on > the screen: > > "Starting local daemons : sysctl :unknown oid > 'hw.atamodes' " This means that the hw.atamodes object ID does no longer exist. I haven't checked a recent 4.X installation lately, but as far as I can tell from a quick glance at the /usr/src/sys/dev/ata source, this is no longer needed. The knobs that you can tweak for enabling or disabling DMA on ata & atapi devices are now called: hw.ata.ata_dma: 0 hw.ata.atapi_dma: 0 You might also want to check out the manpage of the atacontrol(8) utility for a bit more information on 'modes' of such devices and ways to view and/or change the current mode. - Giorgos To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
