Sender: owner-freebsd-stable@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG I'm using 3.3-RELEASE. And, I've got one CD that I can put in the drive. When I do so (if it's the first CD used since booting), I get the following message: Oct 1 09:31:02 lakes su: rivers to root on /dev/ttyp0 Oct 1 09:31:08 lakes /kernel: cd0 at ahc0 bus 0 target 4 lun 0 Oct 1 09:31:08 lakes /kernel: cd0: Removable CD-ROM SC SI-2 device Oct 1 09:31:08 lakes /kernel: cd0: 3.300MB/s transfers Oct 1 09:31:08 lakes /kernel: cd0: Attempt to query device size failed: NOT REA DY, Vendor Specific ASC The mount command will not complete. The CD drive is locked up, as it believes the CD-ROM is in-use. If you cntrl-C to interrupt the mount command, you do get a prompt; but you can't umount the CD (it didn't successfully mount) to clear up the in-use bit... So, you can't get the CD-ROM out of the drive. The only option is to reboot the machine. What's odd about this - is I can use just about any other CD-ROM, it just so happens this one particular one (the clip-art CD from WordPerfect) does this. I don't seem to be able to find another CD-ROM that causes the problem. As you can see - this is an HP 6020i. I'm also using an aha2940uw. It's possible this CD has problems (but it works fine in other machines.) It's possible that an HP 6020 has problems that this CD "tickles" - but, that should not "lock up" the driver. So, my issue is this - how do you clear a "partial mount" without rebooting? - Dave Rivers - To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
