I had fired up xmcd v2.5 pl1 and listened to the CD Stanley Turrentine/Shirley
Scott "Never Let Me Go" which was inserted into /dev/racd0c on the
second IDE controller of a GA-BX2000 (Gigabyte) motherboard while
I had mounted the FreeBSD 3.4 CD # 3 in the second CD ROM drive, a 48x drive
and was executing the command tar cf packages | (cd /c ; tar xvf -)
when the following line appeared on the xterm and the music ceased tp play:

CD audio: ioctl error on /dev/racd0c: cmd=CDIOCREADSUBCHANNEL errno=5

Here is the portion of dmesg:

How-To-Repeat:

intensive transfer on the second drive.
