I am wondering = whether this could be related to this option, which isn=C2=B4t activated in= my kernel config. > We are running a 2.4.25 PPC Kernel with Xenomai 2.4.9. 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. >=20 > Many thanks in advance > Roderik >=20 > -------------------------------------------------------- > manroland AG > Vorsitzender des Aufsichtsrates: Hanno C.
