>Organization:
MyBSD
>Environment:
System: FreeBSD 4.x / 5.1
>Description:
Mounting multisession cd will fail with 'invalid argument'.
This only occur if the very first track of the cd is NOT
a data track, because the atapi-cd driver rely only on the
first track to decide which block_size to use. However the cd
can be mounted successfully through atapi-cam subsystem, or
using older FreeBSD release (2.2.x).
>How-To-Repeat:
Insert multisession cd (perhaps audio + data, where audio is
in first session and at the beginning of the track)
# mount_cd9660 /dev/acd0c /cdrom
mount_cd9660: /dev/acd0c: Invalid argument
# mount_cd9660 -s the_exact_sector /dev/acd0c /cdrom
mount_cd9660: /dev/acd0c: Invalid argument
>Fix:
1) enable atapicam support and mount the cd
using /dev/cd0c (only a workaround).
2) Apply this patch (perhaps fix)
