Re: [CentOS] CentOS 7.3
Hello, I have solved the problem but I don't know why it now works. If I boot the 7.3 USB Key, go to troubleshoot then select installation with basic graphics it all works. I can then boot the system disk and set up the full graphics. As an experiment I tried both 7.2 and 7.4. The above rules apply to 7.2. With 7.4 it works with no problems. To tidy up the boot process 'irqpoll' needs to be included in the boot command line/grub. Thank you for all your suggestions.

Re: [CentOS] CentOS 7.3
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.

Re: [CentOS] CentOS 7.3 and e1000e
What I did on couple of my CentOS boxes is: - use a bridge which is connected to the specific nic(will always look as up after boot) - Run a cron script that checks if the nic state is "NO-CARRIER" or other weird situations like no IP address and try to run ifdown X-nic and then ifup X-nic. Depends on the hardware and situation you might need to choose what fits youe environment as a solution instead of fixing the whole CentOS distro.

Re: [CentOS] CentOS 7.3 and e1000e
This may be the wrong approach, but install the NetworkManager-config-server rpm. It sets a config option to allow interfaces to be configured before being available, which may help.

This is one of the reasons why I continue to use NM for our servers, I’ve been in similar situations (where power is restored to the rack with computers in it before to the rack with the networking equipment). The ‘network’ sysv service just runs once and gives up if it can’t bring up the network. The problem with LINKDELAY= is that it will always slow down the network service (even if the network is fine), and if you set it too high, might cause other services which rely on it to time out. -- Jonathan Billings ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
