Re: BUG: unable to handle kernel paging request at 00007ffd7ce07800

Hi Paolo,

  OK, That did something for the overruns, and Lat max! Will try now with
8 cores.
But there is still some kernel error. It is not too clear what the issue is.
Also calibrate segfaults.

I've attached the details, please let me know if you have any ideas.
Thanks
Doug
