PROBLEM: Can't mount a SCSI emulated IDE cd-rom

Hi,
I will try to follow the suggested procedure for reporting kernel bugs (http://www.kernel.org/pub/linux/docs/lkml/reporting-bugs.html).

1) I can't mount a SCSI emulated IDE cd-rom.

2) When trying to mount the cdrom it writes the error:
"mount: wrong fs type, bad option, bad superblock on /dev/sr0, or too many mounted file systems"

then I run dmesg, and it writes a lot of lines with:

"ide-scsi: expected 2048 got 4096 limit 2048
ide-scsi: The scsi wants to send us more data than expected - discarding data
ide-scsi: [[ 28 0 0 0 0 63 0 0 1 0 0 0 ]
]"

The number 63 is changing. It starts with:
ide-scsi: [[ 28 0 0 0 0 10 0 0 1 0 0 0 ]

and stops at 63.

At last dmesg writes:

"ide-scsi: expected 2048 got 4096 limit 2048
Unable to identify CD-ROM format."

(You can see the entire output of dmesg at the end of this mail).

There is no problem with my IDE CD-Writer. Only the IDE CD-ROM is unmountable. By the way, the CD-ROM is able to play audio-cd's.
