I am having a Red Hat 6.7 running on VM which I updated with the latest version kernel-2.6.32-573.26.1.el6.x86_64. but after this update I received the below error:kernel panic-not syncing: VFS: unable to mount root fs on unknown block(0,0)Previous version was kernel-2.6.32-573.22.1.el6.x86_64 .
Unable to boot after updating the kernel rhel 6.7

I have booted my system with my previous kernel which is working fine. while troubleshooting the system we found that there is no initrmfs image on the system and there is no initramfs line in the grub.conf file. I have created the image with the below command and edited the grub.conf file# mkinitrd /boot/initramfs-2.6.32-573.26.1.el6.x86_64.img 2.6.32-573.26.1.el6.x86_64After this change the system is working fine. possible bug from Red Hat.
