maybe it requires file capabilities support?

if so check your kernel config:

CONFIG_EXT2_FS_XATTR=y
CONFIG_EXT3_FS_XATTR=y
CONFIG_EXT4_FS_XATTR=y
CONFIG_REISERFS_FS_XATTR=y
CONFIG_TMPFS_XATTR=y
# CONFIG_JFFS2_FS_XATTR is not set
CONFIG_UBIFS_FS_XATTR=y
CONFIG_SQUASHFS_XATTR=y
CONFIG_CIFS_XATTR=y

and similar s appropriate for your filesystem, along with your mount
options
