I have rebuilt my CentOS 7 server and on restart, the boot screen locks up, yet I can remote in to the server just fine as through it has fully booted.

Restarting and looking at the boot messages, the last message is:

[   OK   ] Stopped dracut pre-pivot and cleanup hook

How can I:

a) fix the boot process?

or

b) study the boot process to see what is hanging?

One hint is that the BIOS reported it had been reset, however I look at its settings and the date and time are correct, and all other settings look good. I may have touched a reset jumper on the motherboard inadvertently.

More Information:

While the screen update stalls after the message above, after remoting into the system, the /var/log/boot.log file contains the remainder of the boot process. This could point to a graphics issue?

  • What does the boot log and dmesg say when you log in remotely? – Raman Sailopal Oct 4 '17 at 10:28
  • I have updated the question with the boot log information you asked for. Interesting, seems like the boot is fine but the graphics is stalling. – J Collins Oct 4 '17 at 10:47
  • Regarding closure, while it is a rare scenario, it could easily be reproduced by those using an external graphics card. I suspect the site is here to service repeatable issues, no matter their rarity. – J Collins Dec 6 '17 at 11:35

Turns out the onboard graphics had been switched on in the BIOS reset. This meant that for whatever reason, the PCIe graphics card would receive graphical updates up to a point during the boot, then hang on the last update, while the onboard graphics continued to run.

Disabling the onboard graphics in the BIOS has fixed my issue.
