Ocasionalmente mi computadora portátil se bloquea cuando intento acceder a mi directorio personal. La única solución hasta el momento es reiniciar y luego desaparece durante una semana.
/var/log/kern.log tiene el siguiente error:

Solo para mover la respuesta de un comentario a una respuesta adecuada: había un recurso compartido de Windows montado dentro del directorio principal (consulte las referencias de cifs en el seguimiento de la pregunta).
Desmontar este recurso compartido evitó el problema, pero el núcleo del problema aún no se ha resuelto.
