    SubjectRe: Linux 2.1.131ac3
    Hi,

    Michel, and anyone else who is able to reproduce the kernel
    crash, please compile ide-scsi with the:

    #define IDESCSI_DEBUG_LOG 0

    define in line 53 of drivers/scsi/ide-scsi.c changed into

    #define IDESCSI_DEBUG_LOG 1

    This will log the SCSI traffic between/to the ATAPI drive, and
    might help us to see where in particular this drive is responding
    differently than other drives, and which code path is triggered
    as a consequence.
