  Let $R$ be a complete discrete valuation ring with residue characteristic
$p>0$. In this note we give an example of a Galois cover $f:Y\to X$ between
flat and normal formal $R$-schemes of finite type which is \'etale above the
generic fibre of $X$ such that the special fibre of $Y$ is reduced and such
that $f$ doesn't have the structure of a torsor under a finite and flat $R$
group scheme. In the example $R$ has equal characteristic $p$ and the Galois
group of the cover is cyclic of order $p^2$. In the example the formal scheme
$X$ is affine and can be choosen to be even smooth.
