Errores de ACPI en equipos SIATIC e Infolab

Con los últimos kernels vengo observando que, en los equipos HP Prodesk 600 G1 de Siatic y los HP Prodesk 600 G2 de Infolab, se muestran errores de ACPI en el arranque:

Para evitarlo, he añadido "acpi=strict" a las opciones de arranque del kernel. Concretamente, como utilizo refind como cargador de arranque, la he añadido  al fichero /boot/refind_linux.conf:
"Boot with minimal options"   "root=UUID=295ccc39-6183-4e82-a7b3-72fd36efa808 ro quiet splash acpi=strict pcie_aspm=off"
"Boot with standard options"  "root=UUID=295ccc39-6183-4e82-a7b3-72fd36efa808 ro recovery nomodeset"
"Boot to single-user mode"    "root=UUID=295ccc39-6183-4e82-a7b3-72fd36efa808 ro recovery nomodeset single"

Naturalmente, lo tengo automatizado mediante un módulo puppet que gestiona refind.
