>Description:
It appears that when using atapicam, different data is returned from a given CD.
Attempting to rip a cd with cdda2wav once with /dev/acd0c and once with atapicam 1,0,0
gives different results.
The number of tracks is correct with the /dev/acd0c, but other things are problems.
With atapicam, the the number of tracks and times is incorrect -- it is as if the
wrong block is being read as the table of contents.
pc:1# cdda2wav -D /dev/acd0c -O wav -B -d99999 -F foo
cdrom device (/dev/acd0c) is not of type generic SCSI. Setting interface to cooked_ioctl.

>How-To-Repeat:
Use kernel with atapicam, run cdda2wav as above.
>Fix:
Remove atapicam and ata cd drive. Buy a real scsi card and drive.
