Problem during /init execve

so may be its not getxattr, but inode itself is null:

if (!inode || !inode->i_op->getxattr)

you can verify that by breaking if condition into two separate conditions.

There are other options like CONFIG_AUDIT_TREE, disable that too. Also
make sure that initrd image has the ext2 driver compiled for this
kernel.

If you are using vanilla ext2 fs and CONFIG_EXT2_FS_XATTR is set, then
it must be initialized in static inode operations table, look at:
ext2_file_inode_operations for files
ext2_dir_inode_operations for dir
ext2_special_inode_operations for special files
ext2_fast_symlink_inode_operations and ext2_symlink_inode_operations
for symlinks
all of them are compiled and initialized with generic_getxattr if you
compile with CONFIG_EXT2_FS_XATTR.
