>Description:
When boot GENERIC kernel on my VAIO P, the following error occurs.

ACPI Exception (tbxface-0657): AE_AML_NO_OPERAND, While loading namespace from ACPI tables [20080321]
ACPI: unable to load tables: AE_AML_NO_OPERAND

After that, many devices cannot be detected, and then hangup.
it is the same in NetBSD 5.0RC2.

However in NetBSD 4.0,  It normally detects.

acpi0 at mainbus0: Advanced Configuration and Power Interface
acpi0: using Intel ACPI CA subsystem version 20060217
acpi0: X/RSDT: OemId <  Sony,    VAIO,20081208>, AslId <    ,01000013>
acpi0: SCI interrupting at int 9

>How-To-Repeat:
Boot current or netbsd-5 kernel with acpi on VAIO P
>Fix:
This is an acpica's bug.

Fix patch:
