Summary0014792: Kernel Panic booting with 3.10.0-862.2.3.el7.x86_64
DescriptionA kernel panic occurs during boot:

`Kernel panic - not synching: VFS: Unable to mount root fs on unknown-block(0,0)`

This could be related to this: https://askubuntu.com/questions/41930/kernel-panic-not-syncing-vfs-unable-to-mount-root-fs-on-unknown-block0-0

There is a message about TSC_DEADLINE in the line before, which relates to this issue: https://bugs.launchpad.net/ubuntu/+source/intel-microcode/+bug/1724650

This has started happening after upgrading to CENTOS 7.5. In fact, the PC crashed mid-installation, rebooted and displayed the kernel panic message. Now, if rebooting and using 3.10.0-862.2.3.el7.x86_64, the crash occurs. It might be only that the initramfs is missing, as suggested in the askubuntu forum. Sorry, I'm unsure how to get the logs for the initial crash and reboot (from the upgrade). Any hints, I am happy to give it a try.

I can still use the workstation if I boot using kernel version 3.10.0-693.21.1.el7.x86_64.
Steps To ReproduceReboot PC and choose latest kernel version (3.10.0-862.2.3.el7.x86_64) or let the PC boot using this version automatically.

(files above are mine)
I have the same (or at least similar) problem:
PC: Core2Duo E6420 with 2GB RAM
Centos7 x86_64 as KVM host with one Centos7 x86_64 guest worked just fine for years.
Upgrade of the host to Centos 7.5 finished smoothly, but then during upgrade of KVM guest unexpected restart of the guest occured.
After that every boot of the guest with kernel 3.10.0-862.2.3.el7 led to kernel panic.
System with kernel 3.10.0-693.21.1 or 3.10.0-693.17.1 boots as expected but anyway after some time unexpectedly restarts.
I tried to remove new kernel 3.10.0-862.2.3.el7 and reinstall it by "yum update" and found out that attempt to install new kernel causes restart.
No records are added to logs after guest restart on host side nor on guest side.

# uname -a
Linux mypc06.mynet.tld 3.10.0-862.2.3.el7.x86_64 #1 SMP Wed May 9 18:05:47 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

Once I saw this lines on main host console (definitely not everytime when guest spuriously restarts):

I had the same issue. For me it was because the initramfs was missing.
I booted on an USB key and generated it and it was working again.
I used the following commands:

mount /dev/sda1 /mnt
mount --bind /dev /mnt/dev/
mount --bind /dev/pts/ /mnt/dev/pts/
mount --bind /proc/ /mnt/proc/
mount --bins /sys/ /mnt/sys/
chroot /mnt
depmod -aeF /boot/System.map-3.10.0-862.2.3.el7.x86_64 3.10.0-862.2.3.el7.x86_64
dracut -f /boot/initramfs-3.10.0-862.2.3.el7.x86_64.img 3.10.0-862.2.3.el7.x86_64
grub2-mkconfig -o /boot/grub2/grub.cfg
reboot
