Often due to hardware failure... You'll need to check out /var/log/dmesg and /var/log/syslog to get more info about what actually happened. –hsanders Oct 12 '12 at 21:58 1 You should try to boot using a "Live CD", and then mount the HDD partition that held / and /lib. Then try to restore the libc files. –sawdust Oct 12 '12 at 23:43 6 This isn't really the right forum for this question. You're better off asking on superuser.com or ubuntu.stackexchange.com.

Panic occurred, switching back to text console When passing init=option selinux=0 to the kernel at boot the server will boot without a problem. I have tried searching for what init=option does but I have not been able to find any recourses explaining it. Could someone explain what this parameter does? Also, as this is a production server are there any negatives/risks http://serverfault.com/questions/603875/server-wont-boot-kernel-panic-not-syncing in running with the init=option? I have tried to remake the initramfs via dracut which did not work and received the above error upon boot. As this is a clustered server and the primary server should be identical I have copied the /boot drive from the other server but this did not solve the problem either. (The other server does not have this behavior) Restoring /boot from backup did not work either. Could you please help me investigate this problem What causes this kernel panic? How would you go about resolving this issue? What logs (if any) would tell you more information? As this is an older install, would an update/upgrade potentially fix this issue? I would also like to add that the only other possible related issue was that the root disk which was raid mirrored failed and was replaced before this happened.

a comment Kernel panic - not syncing Attempted to kill init Oh Boy we Hate Them…. There are several reasons for the kernel to hang at boot with the line…. Fixing https://www.deep-silver.com/kernel-panic-syncing-attempted-to-kill-init/ Kernel panic - not syncing: Attempted to kill init! In most cases this cause by a faulty SELinux setting most likely on system file label. This can happened if you just upgraded your Linux box or played with SELinux while trying to remove or disable it. Before you can actually try to fix the issue with SELiunx that causing the system to hang at kernel panic boot, you need to get your system booting up again. Here's how to do it. In this example I will be using CentOS 5.9 but these steps should apply to any recent CentOS/RHEL.STEP 01: Restart the server an as soon as you see the boot screen as in the picture below (or similar depend on your distribution), press Esc button on the server keyboard.(you kernel panic not can actually press any key but we want to be safe)Doing so will take you into Boot option menu as in the picture below.STEP 02: Using the ↑and ↓keys choose the first boot menu in this case CenOS (2.6.18.348.18.1.el5) and press A in the server keyboard to get the next screen as below.STEP 03: In this screen menu append this to the end of the line selinux=0 enforcing=0. So the whole line will look like this… grub append> ro root=/dev/VolGroup00/LogVo100 selinux=0 enforcing=0Your line might look other then the example but the idea is to append the arguments to the end of the line.Note that we disable both, SELinux and enforcing, in most cases you will only need one of them however by using both arguments we make sure the system boot even if SELinux is disabled but left enforcing or the targeted policy is missing or corrupted.Once you done appending the arguments to the Kernel boot line, hit Enter and everything went well the system will continue to boot and you should get the terminal login screen as below.Once you have managed to get into the terminal, is now t
