Hola salvari, bienvenido al foro.

Sería conveniente que abrieras tu propio hilo, no sólo porque parece que el usuario que abrió este no regresa para proporcionar la información solicitada, sino porque tu equipo seguramente es diferente y podrías ayudar a otros usuarios con tu mismo equipo si añades al titulo de tu post ese dato (por ejemplo Errores ACPI Lenovo Legion Y540-15IRH-PG0 iniciando Mint 20).

En cualquier caso si lees lo que comento en el post anterior verás que el problema reside en la integración del kernel con la BIOS y en tu caso la BIOS está desactualizada (hay una revisión BHCN38WW de hace un par de meses en la página de soporte de Lenovo).

No hay que obsesionarse con los errores ACPI y en tu caso al final carga las tablas AML y aunque no sean todas (ACPI: 13 ACPI AML tables successfully acquired and loaded),es posible que no necesite más. Como digo suelen ser errores inocuos siempre que no impidan iniciar el sistema y luego funcione de forma adecuada.

La actualización de la BIOS y/o nueva versión del kernel puede hacerlos desaparecer sin más y en caso contrario revisar la configuración de la BIOS para facilitar la labor del kernel evitando funciones en auto o desactivando/activando otras que no se encuentren o si en uso y puedan interferir (como el Secure Boot que no es tu caso, pero si el modo UEFI si inicias en modo BIOS,...). Ello dependerá de lo que muestre la BIOS (cada vez menos por desgracia)

A pesar de ello una de las consecuencias puede ser que el sistema siga con su empeño, entre en bucle ralentizando el funcionamiento, con cuelgues ocasionales y/o que el registro aumente de forma incontrolada. No devuelves el resultado del último código para saber si es tu caso, ni comunicas ninguno de estos efectos secundarios que justifiquen tomar medidas.

Gracias por responder tan pronto.

Abriré un hilo con la información, pero tardaré bastante en actualizar la BIOS, no tengo Windows instalado en mi portátil.

Por curiosidad: ¿cómo sabes que el problema se soluciona con la actualización de la BIOS?

Llevo ya un par de dias trabajando con normalidad con el ordenador, así que creo que no hay funcionalidad afectada.

No lo sé, es mas no es seguro que así sea. Estos problemas son de dos: la BIOS y el kernel.

Las actualizaciones de la BIOS corrigen problemas y realizan mejoras en el comportamiento del equipo o sus componentes. La página de soporte proporciona un README de los cambios respecto a la versión anterior que puedes consultar. Tener una BIOS actualizada facilita la labor del kernel siempre que el fabricante no se aparte de los estándares.

Por su parte las actualizaciones del kernel corrigen también problemas y realizan mejoras. En un kernel relativamente reciente como el 5.4 también aparecen regresiones (olvidos de soluciones a problemas conocidos y que estaba superados en versiones anteriores). Tanto los problemas como las regresiones que se solucionan respecto a la versión anterior son descritos por ejemplo en el gestor de paquetes Synaptic buscando el kernel, seleccionándolo y haciendo clic en el botón Obtener registro de cambios de la ventana inferior derecha. Es de esperar que un kernel con soporte a largo plazo presente menos problemas en sucesivas ediciones aunque las regresiones siempre son posibles.

Puedes no realizar la actualización de la BIOS (conveniente pero no exenta de riesgos) sii inicias sin problemas y tampoco se ve afectada la funcionalidad del equipo.

La actualización del kernel es necesaria aunque sólo sea por motivos de seguridad, pero debes observar si esos problemas desaparecen, se mantienen o se agudizan. En este último caso tienes la alternativa de volver al kernel anterior (en la opciones avanzadas de menú GRUB) desinstalar el último y esperar un nuevo kernel o tomar otras medidas si fuera necesario.

A falta de mas información (el dmesg proporcionado no es el resultado de ninguna de las dos formas solicitadas) es todo lo que puedo decirte.

PD: Como el Administrador ha creído conveniente extraer estos posts del hilo del que formaban parte, el nuevo hilo abierto ya no es necesario ya que tampoco proporcionas ninguna información adicional a la de los post anteriores y puedes eliminarlo (clic en el icono de la cruz de la derecha) para evitar duplicados.
