I wonder if you could help.


I have a requirement to load CentOS 7.3 on to a server. I have the
distribution on a bootable USB key.


CentOS boots to the first menu but when I select the option to install
almost immediately I get the error below:


NMI watchdog: BUG: soft lockup - CPU#82 stuck for 23s! [system-udevd:1221]


The above error is output every 23s


This is a repeatable error condition.


When I load CentOS 7.4 on to the server I get no problems.


When I load the above CentOS 7.3 distribution on to an older server I get no


Has anyone every seen the NMI watchdog error and found a resolution.


Thank you in advance,
