ACPI errors on this specific architecture often relate to power states (C-states) or outdated BIOS.
On older ACPI versions, hibernation files can become corrupt. Use powercfg -h off in Command Prompt to refresh it.
If you expect to see it but don’t, your kernel might have been compiled with CONFIG_DEBUG_KERNEL=n or CONFIG_ACPI_DEBUG=n . The string is debug-level (KERN_DEBUG), so it may be hidden by default. Run dmesg -l debug to reveal it.
