Not a real time kernel?
you probably have to build a Preempt-rt kernel if ubuntu does not supply one

Which variant did you get from the buildbot?
LinuxCNC is not finding a kernel that it recognises as having Realtime.
I guess you followed the instructions here?
forum.linuxcnc.org/forum/27-driver-board...7i77?start=180#62783
Did every step complete without error?

Sorry PCW .... I'm on preemp_rt 4.4.27 on ubuntu 14.04 .... I've compiled the kernel and apply the pacth ..... but linuxcnc run out of rtai .... why?
Please be patient ... now as now I decide if buy more mesa card or not .... depends on linuxcnc ... I took the courage to do this by following your instructions. I thought: pcw work into mesa it does he will know what it says ?? so I followed your steps and I did the installation that does not work ... you have some alternative method ?? I can install anything precompiled? You can indicate me the way? You can show me what you have installed and running with the mesa cards and has good performance to work with a robot delta ??
I've I3 3.6Ghz and 4Gb ram ... on ubuntu 10.04 2800 ns latency test ....

Giorgio

@AndyPugh Tanks a lot (very lot).... I follow the same procedure but with kernel 4.4.27 .... because I've not seen that link that you posted me ... but another ... and the pacth for that isn't avaiable jet ... so I think to use a newer kernel ....
Any how all compile without error ....
If PCW recently use kernel 4.1.5 .... I try ... but the proc is very long ....
regards
giorgio

I would not use a RTAI kernel but rather a Preempt-RT kernel if using Ubuntu14.04

Which version of linuxCNC? You want the "uspace" version for a preempt-rt kernel.

That should all work.
It might be that when you run LinuxCNC you are running the old, installed version, not the new one you just compiled.
If you open a terminal window
cd linuxcnc-dev
, ,/scripts/rip-environment
linuxcnc
You should see
> LINUXCNC - 2.8.0~pre1
