This is the third fresh install of CentOS 7 1708 the last two months that won't boot after a regular "yum update" just after the fresh install has finished.
Define “won’t boot”. Does it stop:
- Before the GRUB2 screen?
- Between the GRUB2 screen and root device mount?
- After root device mount but before entering runlevel 5?
- Something else?
Not really sure. A few times the screen just went black after the grub menu, a few times it stuck waiting on Plymouth to quit.
As for a screenshoot, I'll see if I can find another unused box to try reproducing this on. Don't want to mess up this particular machine.
This sounds like some kind of graphics card issue .. if you see any text that says 'booting CentOS' or a line at the bottom or the '7' grey boot screen, you are past the Grub2 stage.
Are these machines running X windows and a Desktop Environment.
If I had to guess, this is an AMD graphics issue .. or possibly another brand of card.
