Allí lo dice bien clarito: un "Kernel Oops". También conocido como un
bug de kernel. Aquellos que son críticos son llamados "kernel panics",
estos no son tan problemáticos así que son "oops".
Por lo general, cuando ocurren, generan logs del estado completo de la PC.
Empiezan por información del procesador (registros internos):
Apr 18 01:52:29 smtp kernel: CPU: 0

Luego información del proceso (nombre, pid, pila de llamadas de
funciones, puntero de instrucciones, etc.):
