    SubjectRe: [Linux-NTFS-Dev] ntfs OOPS (2.5.63)
    Hi Randy,

    Could you try to turn on debugging in the NTFS driver (compile option in
    the menus), then once ntfs module is loaded (or otherwise anytime) as root
    do:

    echo -1 > /proc/sys/fs/ntfs-debug

    Then mount and to the directory changes. Assuming that you get the bug
    again could you send me the captured kernel log output? (Note there will
    be massive amounts of output.)

    The code looks ok and I can't reproduce here so it would be helpful to see
    if there are any oddities on your partition. Just to make sure it is not
    the compiler, could you do a "make fs/ntfs/inode.S" and send me that as
    well?

    Thanks,

    Anton
