Soory, I seen afterwards you asked for just one,

I had to run cat /proc/cpuinfo to get all info.

Since that looks like a VM, I don't think my theory of what went wrong is correct. There was a bug in the recent microcode_ctl package in the firmware supplied by Intel for certain models of cpu. When the microcode_ctl package was updated, it tried to update the processor microcode and hung the entire system. Thanks Intel! However, since that looks like a VM I suspect you do not have the microcode_ctl package installed at all and if you do then it probably doesn't do anything.

If you run the command virt-what does it produce any output?

KVM is what displays as this the systme I can use on my OVH login and when the system does not wish to reboot, I go to the KVH and the GRUB is showing, not the normal root command line.

I read somewhere that you could boot from the grub ino the new kernel but this would be the first time I ever did this in the last 5 years updating the kernel.

I tried this, but dont know if I used the correct commands as my system could be different - https://www.unix-ninja.com/p/Manually_b ... _from_GRUB

I dont know what to do with this as I need to reboot the system from time to time and if I use kernelcare, it takes care of the kernel, but with WHM and the security advisor, I still need to restart the system.
