Latency spike every 64 seconds? Sounds exactly like SMI to me.

I insmod the rtai_smi.ko module but I am still getting that ~64sec
latency spiking.lax max is usually less than 10K but spikes to
160k.
I noticed for some reason I noticed rtai_sched.ko was not loaded and
cannot be load when rtai_lxrt is loaded.
Is the problem with the rtai_lxrt/rtai_sched co

Once I got RTAI module compiled and working on Debian, installing
LinuxCNC was a lot easier.
After banging my head on the wall for the last couple days, I finally
downloaded the LinuxCNC LiveCD. It install and runs fine. Though
the odd thing is, I can run linuxcnc latency-test, I can't run rtai

thanks for the link. I've tried so many different way to compile
rtai, ie via debian's repository and downloading from original source
that I'm a bit lost right now.However it good to know that at
least someone else is running EMC on debian, so it's a doable task :)
Anyway, I just got the lat

Hi
I have built 2.6.26 rtai kernels on Lenny and Squeeze.
Still using Lenny on an older machine
I used these instructions as a starting point and tailored for debian

My notes suggest that tk/tcl8.4 bwidget and python-tk are not in the
Lenny
I think you are in trouble since the top 4 hits on google for "building
rtai on debian" go to linuxcnc. I have built many RTAI kernels, but it was
always painful, and it has been long enough that I really would rather
change operating systems.

Is there a more up to date tutorial on how to compile rtai with
Debian.It took me a whole weekend to compile a kernel that will
boot but when I try the latency test, I get
