    Can you post the output of 'lsattr <dir>' where you get permission
    denied? Also, please include any relevant dmesg output as well.

    ------------------------------------

    mount /dev/hda1 /mnt/mountpoint-reiserfs
    mount /dev/sdb1 /mnt/mountpoint-ext3

    kernel-2.6.16-rc1-git6 OK

    [bebe@localhost ~]$ cd /mnt
    [bebe@localhost mnt]$ lsattr
    ------------- ./mountpoint-ext3
    lsattr: Inappropriate ioctl for device While reading flags on ./mountpoint-reiserfs
    [bebe@localhost mnt]$

    [bebe@localhost mnt]$ cd mountpoint-reiserfs
    [bebe@localhost mountpoint-reiserfs]$ lsattr
    lsattr: Inappropriate ioctl for device While reading flags on ./v
    lsattr: Inappropriate ioctl for device While reading flags on ./tmp

    [bebe@localhost mountpoint-reiserfs]$

    kernel-2.6.16-rc1-git6 OK

    -----------------------------------

    kernel-2.6.16-rc2-git9 BAD

    [bebe@localhost ~]$ cd /mnt
    [bebe@localhost mnt]$ lsattr
    ------------- ./mountpoint-ext3
    su---ad-cjI-- ./mountpoint-reiserfs

    [bebe@localhost mnt]$ cd mountpoint-reiserfs
    [bebe@localhost mountpoint-reiserfs]$ lsattr
    s-S-i-dAc--t- ./v
    s-S-i-dAc--t- ./tmp

    kernel-2.6.16-rc2-git9 BAD

    looks like system automaticly sets attribs mounting reiserfs

    "A file with the `i' attribute cannot be modified: it cannot be deleted or renamed, no link can be created to this file and no data can be written to the file. Only the superuser or a process possessing the CAP_LINUX_IMMUTABLE capability can set or clear this attribute."

    "A file with the `a' attribute set can only be open in append mode for writing. Only the superuser or a process possessing the CAP_LINUX_IMMUTABLE capability can set or clear this attribute."
