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 ) |

Hi, I am seeing the same issue, I am using centos7.8. I start with kernel 3.10.0-1062.9.1, then I upgraded to kernel 3.10.0-1127.19.1 and my system will not boot using the new kernel. if I choose the old kernel from the grub menu it boots fine. this is my pre-production test machine using Virtualbox. unnamed.jpg (57,990 bytes) |

Both screenshots here look like the usual crash you get when yum has been interrupted during the kernel package install and it has half installed the kernel. In this situation then kernel itself is installed and added to grub but yum generates the initramfs file for it in the cleanup phase so if it's interrupted between those two then you end up with a kernel installed that has no initramfs. Either remove that kernel and reinstall it or `yum reinstall kernel-3.10.0-1127.19.1.el7` or run dracut -f --kvers 3.10.0-1127.19.1.el7 (or some variation on that, not tested so please test before use!). Obviously you will need to boot an older kernel to do that and then reboot into the new one again. |

I reverted from a snapshot. did an upgrade with --exclude=kernel* and --exclude=linux-firmware*.rebooted with no issues. Next, I made a snapshot and I upgraded with only --exclude=linux-firmware* (this was a suggestion I found in another thread) and it booted properly. I made a snapshot again, then upgraded just the firmware. I rebooted with no issues. It looks like you are correct TrevorH it was that the new kernel installation was interrupted. thanks. :) |
