In the mean time I have found that kernels 2.6.15 and 2.6.16 do not suffer from this problem, whereas 2.6.22 till 2.6.25 do. Testing for kernels 2.6.17 till 2.6.21 is somewhat complicated in my setup, because there are other problems (NFS-related) which I need to sort out. So it looks like there is a bug somehow. Providing the dxs_support parameter does not make any difference, no matter what value I set it to. Z.
