The cdrom driver does not fill any isofs structures. He just reads the blocks, nothing else...

SCSI CD drive is an old Toshiba 3301. ^^^^^^^^^^^^^^^^ Well, that's a real old one. It can not read XA (Form2) sectors, IIRC. Maybe it gets confused by the Form1/Form2 switching logic in sr_photocd(). You could try to comment out the call to sr_photocd (in sr_open(), sr.c) and see if it makes a difference. If this does not help, the drive is probably just to old to read the CD-ROM.
