Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-stable@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG I'm running 3.1-RELEASE, and was going to use a 3.1-STABLE CD-RW to upgrade from (after doing a make buildworld on a 3.1-STABLE system). However, the 3.1-RELEASE CD-ROM drive fails to read the CD-RW disk prepared on the 3.1-STABLE system. Here's the appropriate export from dmesg: wdc0 at 0x1f0-0x1f7 irq 14 on isa wdc0: unit 0 (wd0): wd0: 696MB (1427328 sectors), 1416 cyls, 16 heads, 63 S/T, 512 B/S wdc0: unit 1 (atapi): , 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 The message from the system is "acd0: read_toc failed" when I try to mount it. Further, I get the same error from commercial CD-ROMs until I power cycle the drive after that, after which it can handle CD-ROMs just fine. As a final note, under 3.0-RELEASE this drive worked fine with CD-RWs. Any suggestions would be a great deal of benefit, as the ability to read CD-RW disks is important for the intended use of this machine. Thanx,
