I have been using Ubuntu 10.04 with LinuxCNC for about 3 years with very
good results. I downloaded http://linuxcnc.org/binary.hybrid.iso with the
thought of upgrading. I installed it to a new drive. I can startup and run
ok until I try to run any of the LinuxCNC apps. The machine does not

What about RAM ? (How many GB do you have?)
I do believe that with the new installation you are no more running with
the vesa driver .
Can you double check this ?
Did you already make the isolcpus=1 modification ?
I hope it is not a kernel issue due to the old hardware .

As I understood the isolcpus=1 (for a dual core processor) is "mandatory" .
I you have multiple cores 4 or 8 (but you shouldn't) there is a different
isolcpus setting to optimize the RTAI results (aka latency).
Have you tried to let the GPU drivers as the installation process load
automagically.

When you switch to a new version of the RTAI kernel you should re-run
the latency test. The new kernel usually works better (i
Hi Sebastian .
Is the base thread period adjustable for the latency test gui ?
If yes , can you please tell me how can I do this ?

You don't need to set a base period to run the latency test. Just run
it, and it'll measure the latency, and you use that to pick a ba

I misunderstood you comment . :-)

Bummer.
Can you send us the output of 'dpkg -s linux-image-3.4-9-rtai-686-pae'
and paste the output of dmesg somewhere?

No, it is not. It can help improve realtime performance, but it by is
not mandatory by any means.

That's correct.
I noticed this in your boot messages, i have no idea if it's related to
your lockup:
