Kernel 3.10.0-957.1.3.el7 breaks neth server

Hi everyone,

I had the latest 7.5 version of nethserver serving only as a domain controller (samba 4.7.10). I started the new upgrade on NethServer release 7.6.1810 (final) (samba 4.8.6) and after the upgrade everything started to go wrong… i could not ping my AD IP address, nethserver IP, web gui was not working, yum couldn’t resove (but the ping was working towards the internet) etc . Checking it with systemctl, everyhing was running, no errors in journal.
After two hours of restarting, searching, I lowered kernel back on 3.10.0-862.14.4.el7.x86_64 and everything returned to normal.
Did anybody had similar problems?

What is the hardware of your server, does it could special?

VM, Hyper V generation2 - MAC spoofing is on
baremetal hardware Supermicro (something exotic)

you are not alone :’(

more generally, this is what my request : Supermicro 3.10.0-957.1.3.el7

In short, your hardware is not compatible with centos7.6, you should upgrade something, either the kernel, or the kmod like you can find in the link.
