I don't recall ever having this issue prior to switching disk names to ada from ad, I can confirm this behaviour - switching back to the ad device and using atapicam to access the DVD works correctly. My only conclusion is that it's a regression in the ATA_CAM code-path, imb ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org

Why on earth would anyone want to use ATA_CAM these days? Because there is still a lot of legacy controllers, while ata(4)'s bus management code is buggy in some aspects, that are difficult to fix without complete rewrite. ATA_CAM wrapper replaces all that problematic code and works better now. -- Alexander Motin ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org

Well, I am not sure if you really meant ATA_CAM and not ATAPICAM? But in case you meant it, for people who do not use SATA-capable hardware, ATA_CAM is useful. This laptop may be no longer be the most recent model these days, but runs -CURRENT just fine most of the time. Also, if I remember correctly, for people with a bit more recent controllers ATA_CAM offers other advantages, but those do not affect me.
