The new kernel for CloudLinux 5.x is based on previous 2.6.18-408.el5.lve1.1.62 and solves the issue that caused kernel to crash. There is no other changes in that kernel.
Please, remember that you need to update CageFS and lve-utils to use new kernel:
To update:
yum install kernel-2.6.18-408.el5.lve1.1.63 --enablerepo=cloudlinux-updates-testing If you have PAE, xen or Enterprise kernel -- use corresponding prefix, like: kernel-PAE, kernel-xen, kernel-ent instead of kernel
