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

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."
