It does not look like any of the developers is reading
these bugs, but I'll submit anyway.

When I mount a multi-session DVD disk created on
Windows using Nero the system freezes.

When I mount in text mode I can actually see what's
going on - there is an endless loop of printk's running
on my screen yelling - "__find_get_block_slow() failed".

My system : FC2, kernel 2.6.7, ATAPI DVD drive, no scsi
emulation.

Same disk reads OK on Windows. Reading CDROMs works OK.

    One more comment - DVD was created using Nero Express 6. DVD
    drive is LITE-ON DVDRW SOHW-812S

    Offline we were also told:

    Nero Express 6, which was bundled with my LITE-ON DVDRW SOHW
    -812S. on windows of course. Create a multi-session DVD.

    At first, I did not close the session and when I saw this problem I thought
    that closing the session would help, but it did not.

    I'm going to try to create a not multi-session DVD and post the result.

    I raised the priority here to match the related bug:

    [ 1008156 ] multi-session starts where
    https://sourceforge.net/tracker/?

    Update - sorry guys, but it turns out that the disc was
    iso9660, not udf.

    My mistake.

    It's still a bug, though - I belive udf should report an
    error message and fail, instead of running in infinite loop.

    I think now in linux_udf discussion we've been told -t udf -o session=$n
    works around this trouble. It is only the default mount of multi-session
    that we're hoping to fix.

    I think at linux_udf we've been told,

    -o session=$n works around the infinite loop in the kernel reported here.

    I also encounterd this problem with a DVD+R I burned. I
    burned it with K3B and it can be mounted properly before I
    add files so the total size reached 4GB. K3B (In fact,
    mkisofs) doesn't allow generate DVD image larger than 4GB. I
    cannot close the disc now. Is there udf file system limit?

    I created this DVD+R in K3B and select UDF/Rock Ridge/Joliet
    (all 3) file systems on it burner is LG HL-DT-ST DVDRAM
    GSA-4040B.

    Now I must disable the "automatically mount removable media"
    option in FC4.

    Sincerely,
    ChenLi Tien
