|Issue||After updating NW hosts from 10.6.0 to 10.6.x, the newly installed kernel panics with following error.|
|Cause||New Kernel ram disk image(initramfs) does not contain the module.dep file as the file was not installed properly during the kernel update. Or the dep file was corrupted during the update.|
Mostly this happens when installation package upload/download was not completely done due to slow network latency between SA Head repo and Hosts.
This is a known issue from RHEL/CentOS 6.
|Resolution||1. Reboot with the previous kernel on Grub in order to rebuild the initramfs file for the new kernel.|
2. Rebuild "modules.dep" file to generate missing dep files for the new kernel which led the kernel panic. i.e. "2.6.32-573.12.1.e16".
3. Rebuild initramfs file for the kernel version to generate the new initfamfs file to reflect the dep file generated in the previous step.
4. Reboot with the new kernel
