Estaba usando zoom y estos mensajes aparecieron en el archivo /var/log/syslog de mi computadora portátil. Estoy usando Ubuntu 19.10 en un Lenovo Thinkpad X220i. Mi versión del kernel es: 5.3.0-42-generic

La computadora de mi amigo empezó a hacer esto, él no la usa como laptop, está inmóvil conectada a un televisor. Está visiblemente polvoriento y es difícil mantener la temperatura de la CPU en el rango de 90-95 ° C. Ya ha quitado el polvo antes y luego se mantiene lo suficientemente frío como para no inyectarlo, así que estoy seguro de que en su caso esa es la solución.
Sé que estoy necroando un hilo viejo, pero lo más probable es que si esto sucede, tengas polvo en el sistema de enfriamiento. O bien, el sistema no está suficientemente refrigerado por diseño (a algunos proveedores parece encantarles tener configuraciones sin ventilador con CPU que realmente necesitan un ventilador, o mantener el ventilador a baja velocidad cuando está lo suficientemente caliente como para rendirse y aumentar un poco).
