I can imagine that it is easiest to just use a machine that does not
have the issue. Especially when having to finish pro
Hi,
My new plan was to avoid the issue by simply using another machine. We
just received a fujitsu esprimo.
About the dell, I proposed to keep it as it was in case it could be
useful for the community for me to do some tests, but you mentioned it
was not necessary as you already had a machin
Vincent,
did you have a chance to try the mentioned patch? It should allow you
to use the machine you wanted to use from the start.
While it might need some more work to get something like this mainline,
i think it is worth trying. But for that to work we need to collect
more information and try s

Hi,
Thanks a lot for the help and insight.
Feels like trying my luck on a different machine is the most
straightforward way to get a working setup. Also I may lack the the
skills to look into this in a truly useful manner. I will try installing
on a fujitsu celsius and see how it goes. If I c

Here the result of clocktest ...
I understand that does not look good at all ?
== Tested clock: 0 (CLOCK_REALTIME)
CPU ToD offset [us] ToD drift [us/s] warps max delta [us]

Hi,
I set tsc=reliable, and "skipped synchronization checks as TSC is
reliable" showed up in the syslog.
The machine boots correctly on both the patched and non patched kernel.
And in both case everything seems to run fine. On xenomai patched kernel

I checked the syslog when booting on the non realtime kernel, and indeed the
same messages related to TSC showed up. Yet, I do not experience any of the
issues observed on the patched kernel (e.g glxgears or keyboard)
I ran lstopo and lshw and there seem to be 2 sockets with 12 cores on each.

Hi,
Many thanks for the answer.
We use new hardware. I am working on a recent dell precision T7910. I did not
try to update our older hardware (still in use).
Info on the CPU of the new machine:
-
processor : 23
vendor_id : GenuineIntel
cpu family : 6
model : 63

Hi,
After using for years xenomai 2.5.6 on ubuntu 12.04, we decided to upgrade to
ubuntu 14.04 and a newer machine.
I installed xenomai 2.6.4 and kernel 3.14.39.
The installation boots correctly, the latency is low and our software seems to
work ok.
But the system has "frequency surge" (I could
