From: Stefan Eggers To: freebsd-gnats-submit@freebsd.org, obrien@NUXI.com Cc: seggers@semyam.dinoco.de Subject: Re: bin/5134: cdcontrol will eject a mounted CDROM Date: Mon, 15 Jun 1998 20:17:46 +0200 Quote from the report: Insert a CDROM into your SCSI cdrom drive. mount_cd9660 /dev/cd0a /cdrom /usr/sbin/cdcontrol eject Insert a different CDROM into your cdrom drive ## OPPS! forgot to umount it first umount /cdrom BANG! reboot. I did something similar. I had a CD mounted and at the same time xmcd was running waiting for an audio CD. The interesting part is that I have xmcd configured to unlock the tray and it did this though the CD was mounted. I opened it by accident, saw what I did and closed it again. Before the drive recognized that I inserted a CD (my 12x SCSI CD drive takes some time for this) I did an unmount on it and got a panic. To get a useful message for the problem report I did it again but this time I made sure that I had the console in front of me at the time of the panic instead of the X11 screen. Thus I read: panic: vref used where vget required Maybe someone has an idea what went wrong or even how to prevent this from happening. Stefan.
