I take it then that you do not have any third party modules then. In which case, it will be just fine to reboot with an older kernel. Just change the default entry set in grub.conf.

Changed last night and so far am fine. There's one difference to the new kernel. The old kernel cannot load the new microcode. The new microcode.dat seems not to correspond well with the older microcode.ko. It throws an error. As I understand that is not a problem unless the CPU has a bug that manifests in my environment/usage. It's too early to say the crash problem is fixed, but I wonder if it is actually the new microcode that caused the problem.
