I am wondering whether this could be related to this option, which isn´t activated in my kernel config.

This option is not related to the issue, it's basically to compile in
the support for select() over RTDM fildes. Your issue is likely related
to a bug in the RPI protocol, we did fix some bugs in this area in
2.5.x.
Try disabling CONFIG_XENO_OPT_PRIOCPL to check whether it helps.
