Hi all,

Just to follow up this, I checked a twin machine of the affected one. 
UEFI has a "Reboot system on NMI" option that I just changed to false. 
Proxmox has been installed to this server and added in cluster to the 
originally affected one. I have seen the NMI message since in the twin 
server, but the server continued to run well, so it seems this will fix 
the reboot problem.
