STATUS_ACPI_ACQUIRE_GLOBAL_LOCK

STATUS_ACPI_ACQUIRE_GLOBAL_LOCK concerns the ACPI Global Lock, a synchronization mechanism described by the Firmware ACPI Control Structure and exposed to AML through the predefined _GL mutex. It coordinates access when both firmware and the operating system can touch shared ACPI-controlled state.

This is not the same thing as a normal application mutex timeout. The relevant evidence is which AML field or operation required the lock, whether the access used a lock rule, and what platform firmware or driver activity could be holding or preventing the lock at that moment.

The ACPI Global Lock could not be acquired

Record the access path, operation region, lock rule and current power or sleep transition.
Correlate repeated failures with firmware updates, embedded-controller activity and device-power transitions.
Keep STATUS_ACPI_MUTEX_NOT_OWNED separate: that status concerns AML mutex ownership, whereas this one concerns acquisition of the ACPI Global Lock.
