I have a Dell Latitude LM Laptop whose ATAPI cdrom drive seems to work
fine when mounting a cdrom (I can run a find /cdrom -print and get
no errors).
However, when I try to play a CD, I get all kinds of problems.
When I run cdcontrol -f /dev/wcd0c, I can acutally do an "info"
command:
cdcontrol> info
Starting track = 1, ending track = 12, TOC size = 106 bytes
track start duration block length type

However, when I try to play a CD with debugging on, I get the following
from syslog:

Any ideas?
Would one of the 3.0 SNAP's code work better?
