Hello Juergen, I've checked again this problem in versions 3.10 and 3.11 and I can confirm the problem exists. But the problem doesn't reproduce in versions 3.9 or previous. It also doesn't happen with kernel 3.14 (using it with the BSP-git version you told me). Have you tried to reproduce the problem with version 3.10(LTS)? Regards, Stella.
