The kernel error message is: acd0: read_toc failed IDE-CDROM drive is a Cyberdrive 24x, jumpered as slave drive on primary IDE channel. Portion of dmesg: wdc0 at 0x1f0-0x1f7 irq 14 on isa wdc0: unit 0 (wd0): <WDC AC2850F> wd0: 814MB (1667232 sectors), 1654 cyls, 16 heads, 63 S/T, 512 B/S wdc0: unit 1 (atapi): <ATAPI CDROM/V2.10>, removable, accel, dma, iordy acd0: drive speed 4125KB/sec, 128KB cache acd0: supported read types: CD-R, CD-RW, CD-DA acd0: Audio: play, 255 volume levels acd0: Mechanism: ejectable tray acd0: Medium: CD-ROM 120mm data disc loaded, unlocked >How-To-Repeat: 1. Open IDE CDROM drive tray, insert any ISO-9660 CD (for example, insert FreeBSD disk 1.) 2. Push tray in. 3. mount /cdrom 4. umount /cdrom 5. Open CDROM drive tray, then close again. 6. mount /cdrom 7. You should see the following message on the console screen: acd0: read_toc failed The only way I have found to work around the problem is to do a hard reset (i.e. shutdown -h now, turn off machine, turn on machine.) Note that a soft reset (shutdown -r now) will not make the problem go away. >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
