Summary0017251: Kernel panic at boot after upgrading kernel to version 3.10.0-1062.18.1.el7.x86_64
DescriptionHi,

We have a big enviroment with multiple Centos 7 Servers. We have als installed a new Hyper V environment where the VM do there thing. The problem is that kernel version 3.10.0-1062.18.1.el7.x86_64 doesn't boot and gives a kernel panic. If i switch back to kernel: 3.10.0-1062.9.1.el7.x86_64 it boots fine.

See attachment for the panic and every time it boots with the kernel it crashes. This is breaking our patch round.
Steps To ReproduceInstall hyper V with:

Microsoft Windows Server 2019 Datacenter
Hyper-V version V3.

Upgrade kernel of VM running centos 7.7 from kernel 3.10.0-1062.9.1.el7.x86_64 to kernel 3.10.0-1062.18.1.el7.x86_64. After a reboot the server will not boot anymore. See attachment.

Unfortunately your pic does not include the first lines of the panic message, where the real cause is usually mentioned.
Anyway, since CentOS 7.8 ( via the CR repository of 7.7 ) is on the market for a week already, please test using kernel 3.10.0-1127.el7.x86_64 which is included in it. You can do that by using yum update --enablerepo=cr ( or even yum update kernel --enablerepo=cr if you are willing to risk a bit of cherry picking, a process which is not really supported though even if it is possible )
