Hay informes de que la coherencia de la cach\u00e9 del pagetable walker no es constante en todos los dispositivos SDM845/850, lo que provoca bloqueos y reinicios. Funciona correctamente en algunos dispositivos (como el Dragonboard 845c, pero no tanto en el Lenovo Yoga C630). Lamentablemente, esto parece ser un fallo en el desarrollo del firmware, ya que, probablemente en alg\u00fan lugar de la vasta pila de hipervisores, se introdujo un cambio para adaptarlo despu\u00e9s del lanzamiento inicial del software (que suele servir como base para los productos). Revertir el cambio para evitar conjeturas adicionales sobre fallos. Esto revierte el commit 6b31a9744b8726c69bb0af290f8475a368a4b805."
