This is my first post here, so please forgive me for any formatting/protocol issues.
I've been having frequent difficulties with a new CentOS 7 machine set up for work. This machine was purchased a few years ago, and due to various reasons was recently formatted to be swapped in to replace an older machine. Coworkers put together an installation checklist for the CentOS machines to ensure configuration control because the programs we use on the machine are very finicky with the installation, user setup, and permissions. Following this checklist, I have installed a set of 4 computers prior to this machine according to the installation checklist without significant issue.
Hence my confusion and frustration when this specific computer, one with identical hardware to another functioning computer, began failing on boot at "Started GNOME Display Manager."
Consultation with coworkers early on resulted in a recommendation to re-install CentOS from scratch. I did so, and after following the checklist and bringing the computer configuration up to match the sister computer, the computer once again starting hanging on boot at "Started GNOME Display Manager." After searching to try and find guides as to why the boot was failing, I verified the installation of LightDM and disabled the Gnome Display Manager (systemctl enable lightdm.service; systemctl disable gdm.service). Upon restart, the boot again hung with the following displayed text:
"[ OK ] Removed slice User Slice of mfe.. Systems..utdown.... DKMS.n.on....ta.576/200385536 blocks"
I observed the same issue after re-enabling the Gnome Display Manager, and it no longer hung at "Started Gnome Display Manger"
I am able to access the computer only through rescue mode, and any attempt to switch to multi-user or graphical mode results in a hung computer. I am out of ideas. I do not know what is happening when an identical configuration on one computer results in a hung boot while the CentOS machines work perfectly well on 4 other computers. I have beaten my head against the wall trying to figure out what is happening. What is going on, and how can I get the computer to start normally?
Information about this computer configuration:
- Graphics card is Quadro P600, uses NVIDIA drivers
- I9 Processor on an X-299 Motherboard
- CentOS 7 is up to date. After re-establishing a network connection in rescue mode, I was able to run 'yum update' to verify recent programs and files
- Nouveau video driver is disabled.
- Grub command line includes: quiet nomodeset modprobe.blacklist.nouveau nouveau.modeset=0 rd.driver.blacklist=nouveau plymouth.ignore-udev
- A file to blacklist the nouveau driver exists at /etc/modprobe.d/blacklist.conf
- Research indicated that the proper driver is kmod-nvidia, and configuration has the elrepo catalog installed.
- kmod-nvidia version installed is kmod-nvidia-450.57
- CentOS 7 Kernel version is 3.10.0-1127.13.1
