I am no computer guy, so I have no suggestions, my only conclusion is
- bad luck...

Oh yes, I have isolcpus=1!
No special hyperthreading disabling though.

Do you have isolcpus set? That might help. My D510 actually gives RT

I have to admit that I was able to run latency test for a short time interval.
Max jitter was 7300 ns.
Nevertheless I am running it with a 0,75 ms servo period, which gives
update interval of 1,33 kHz and I have never had any messages about
realtime delays.
The machine has 7i43 board, which runs 6

By the way, which latency do you have?
My D525MW shows up to 18000 with 2 glxgears running for several hours.

Hello, folks!
I got the BIOS version that is on the D525 board.
I also ran a short latency test.
Few days ago I was asked if I could add that to wiki page. I would
gladly do that, but...
Which page should I post it in?
This one?
