The kernel witch is used by default: v4.4.x-ti-xenomai is part of
Xenomai 3.0.x.  Whereas the 3.8.13-xenomai kernel is part of Xenomai
2.6.x

Since you have a classic BBB, you can safely down-grade to the 3.8.13 kernel

cd /opt/scripts/tools/
git pull
sudo ./update_kernel.sh --bone-xenomai-channel --stable

[Machinekit] Autobuilt jessie image with kernel 4.4

[Aivaras Spaicys]

Its my first time trying to use linuxcnc/machinekit so please excuse me. By 
flowing tutorials and readme's from beaglebone page I downloaded machinekit 
prebuild SD card images based on jessie kernel 4.4.x 
from 
http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#BBW.2FBBB_.28All_Revs.29_Machinekit

Booted it on BBB with no modifications to anything it seems I can't start 
machinekit or latency_test they all give similar output


Starting Machinekit...
Warning - /usr/libexec/linuxcnc/rtapi_app_posix not setuid
'sudo make setuid' missing?
/usr/bin/realtime: line 192: /usr/libexec/linuxcnc/rtapi_app_posix: No such 
file or directory
rtapi_app startup failed - aborting
halcmd: cant connect to rtapi_app: -1 (uri= 
uuid=a42c8c6b-4025-4f83-ba28-dad21114744a): rtapi_rpc(): reply timeout


No readme's anywhere talk about any initial configuration or building 
something (reference to make)

I am probably missing something very simple, or could be that auto builds 
have problems. Currently trying the 3.8.x kernel flavour one, will post on 
the status
