>Description:

        since upgrading to something fairly -current a few weeks ago my laptop
        has spewed the following messages on the console every 5-10 seconsd:

        ACPI Error (dsmethod-0325): Cannot acquire Mutex for method [SX45], 
current SyncLevel is too large (1) [20080321]
        ACPI Error (psparse-0627): Method parse/execution failed [\_SB_.BIF_] 
(Node 0xc2cb10a0), AE_AML_MUTEX_ORDER
        ACPI Error (psparse-0627): Method parse/execution failed 
[\_SB_.BAT0._BIF] (Node 0xc2cb4fe0), AE_AML_MUTEX_ORDER
        acpibat0: failed to evaluate _BIF: AE_AML_MUTEX_ORDER

        this fills my dmesg & logs and is pretty annoying.

>How-To-Repeat:

        boot netbsd on dell inspiron 8500.
