After successfully updating three CentOS 6.3 VM guests to 6.4 I decided to update the host as well, and it failed to boot.
Kernel panic – Not syncing: Attempted to kill init!
Pid: 1, comm: init not tainted: 2.6.32-358.2.1.el6.x86_64 #1
Plus a call trace I couldn’t see
Luckily I was able to boot from the previous kernel and get my system back up. After booting to the previous kernel I removed the “358” kernel and all of it’s related module and devel packages using yum remove, then did yum update again, as I could only guess that the install somehow didn’t complete. But it still fails to boot.
Now the kernel panic has happened to a 6.3 VM guest I upgraded, now it isn’t just the host hardware that is a problem.
Has anyone else seen this?, Any ideas where to start troubleshooting?
