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