My kernel .config file

I have gentoo distro (gentoo pathced kernel). I attach my .config file.

I'm trying to mount bluray disks (in particular for instance Disney cartoon of Mulan and Rapuntzel).

I got this error in console:

# mount /dev/sr0 /mnt/cdrom/
mount: /dev/sr0 is write-protected, mounting read-only
mount: mount /dev/sr0 on /mnt/cdrom failed: Stale file handle

And this is the dmesg output:

[  224.725433] UDF-fs: warning (device sr0): udf_find_metadata_inode_efe: metadata inode efe not found
[  225.061052] UDF-fs: warning (device sr0): udf_find_metadata_inode_efe: metadata inode efe not found
[  225.061055] UDF-fs: error (device sr0): udf_load_metadata_files: Both metadata and mirror metadata inode efe can not found
[  225.061056] UDF-fs: error (device sr0): udf_load_partdesc: error loading MetaData partition map 1



The same specifying the filesystem:

# mount -t udf /dev/sr0 /mnt/cdrom/
mount: /dev/sr0 is write-protected, mounting read-only
mount: mount /dev/sr0 on /mnt/cdrom failed: Stale file handle


I tried also these (I read something about in some forum):

#  mount -t udf,iso13346 /dev/sr0 /mnt/cdrom/
mount: /dev/sr0 is write-protected, mounting read-only
Can only open '/dev/sr0' as read-only
NTFS signature is missing.
Failed to mount '/dev/sr0': Argomento non valido (*=not valid argument)
The device '/dev/sr0' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?


# mount -t udf,iso9660 /dev/sr0 /mnt/cdrom/
mount: /dev/sr0 is write-protected, mounting read-only
Can only open '/dev/sr0' as read-only
NTFS signature is missing.

In my kernel I've set udf support to <m> and the module is loaded:

# lsmod | grep udf
udf                    79861  0 

I tried also to compile kernel with udf inside and not as a module, but nothing changes.


I filed thins bug even in gentoo buzilla, but I think it is better to file here.
