[Xenomai-help] problem with xeno_nucleus.xenomai_gid boot option

[Jonas Buchli]

dear all,

i am trying to setup a xenomai system to run RT tasks as a non-root 
user, we are adding the xeno_nucleus.xenomai_gid kernel option, but 
dmesg gives the following output:

---------------------------------------------------------------------
embedded-pc104:> dmesg | grep gid
Kernel command line: root=UUID=d6b0719f-bd4b-4420-9a20-8d732c90f153 ro 
lapic console=ttyS0,115200n8 console=tty xeno_nucleus.xenomai_gid=1002
Unknown boot option `xeno_nucleus.xenomai_gid=1002': ignoring
---------------------------------------------------------------------

however, the first trick described here works:
http://www.xenomai.org/index.php/Non-root_RT

--------------------------------------------------------------
embedded-pc104:> sudo modprobe xeno_nucleus xenomai_gid=1002
--------------------------------------------------------------

any idea what we are missing?

thanks & best regards
jonas
